Surly Big Dummy Cargo Bike - Load it up and Ride!

Welcome to the wonderful world of hauling stuff on your bike.

Here at Warm Planet Bikes, we love to see people ditching their car and loading up their cargo bike. If you come in to the store, we can help you find the best option for you.

For tons more information see Surly's page: Getting the Most From Your Big Dummy

Looking for something with a little more juice? Check out the Yuba elMundo (Electric Bike)

 "Like all our frames, it’s made of steel and sports lots of little touches that you’ve come to love in a Surly, like clearance for bigger tires and common component sizing. Figure on being able to carry about 200 pounds (90kg) of cargo. The load weight, and how it’s loaded, will affect the handling somewhat. Also, plan on using gears, especially as cargo weight increases. This may seem obvious, but as you get comfy with it you’ll use your full range of gears as never before.

The parts kit is good quality, and suitable to loaded as well as unloaded riding. It’s got a 3x9 drivetrain, Avid BB7 mechanical disc brakes, Shimano Deore hubs, derailleurs and shifters and 26 x 2.1˝ Continental Town & Country tires. We’ve outfitted it with our own Surly bags, deck and rails kit…everything you need for the majority of stuff you might carry, like groceries, shovels, bags of charcoal or mulch, guitars, lamps, mannequins, whatever. Bags, deck and rails are all designed to improve on previous offerings and work together to make sure your stuff is transported with safety and stability.


The beauty of the Longtail standard is that it is an open design, meaning you can find other stuff to fit the system. Xtracycle in particular makes a lot of great stuff to expand what you can haul and how you can haul it, and many people have manufactured their own plug-in pieces when their needs outstripped what was available. Get creative, and get hauling." — Surlybikes.com

Maybe It's Time For A New Saddle

Do You Feel Pain When You Ride? Your Saddle Could Be The Problem

How comfortable a seat feels has a lot to do with where your sit bones (those bones you feel when sitting on a curb or bench) rest on the seat. Ideally, those bones will rest on the saddle's padding. If you've been using a seat for a while you can usually see indentations formed by the bones, which allows gauging whether or not the seat is appropriate for your anatomy.

It's hard to predict which seat will be right for a given rider. Sometimes a wider seat solves pain and other times the narrow ones do the trick. It's all a matter of which seat suits your body shape. For starters, the wider your pelvic anatomy, typically the wider you want the seat to be.

Modern Seats Offer Improved Comfort
Over the years, more amazing seats have been designed than probably any other bicycle component. And today, there's still a wide array of models to select from, some with fairly wild shapes. One feature shared by many of these seats is a cutaway in the saddle top designed to relieve pressure on sensitive tissues in the genital area. Our customers have found these saddle types to be particularly helpful for eliminating problems with numbness. There are also models that have softer sections in the center of the seat designed to work the same as the cutaway.

Another pressure-point eliminator is gel. Some seat makers use this in the sensitive areas to prevent pressure that causes pain and numbness.



Wear Cycling Clothing

When trying seats, be sure to do so wearing your cycling clothing because if you're wearing pants with seams in the crotch area, you'll feel the seams and won't be able to judge the seat comfort. Also, after putting on a new seat, it's best to re-check saddle height because the shape of the new one may be a little taller than the one you've been using. If a seat is too high or too low, you'll feel discomfort from the incorrect seat position and won't be able to feel whether the seat is an improvement or not. The easiest way to match seat height is to measure it before you remove your original seat. You'll then have the exact height to place the new seat and you won't have to experiment to find your optimum position.

Electric Cargo Bicycle: Yuba elMundo is the Future

Fun, Powerful, Green, Electric — Yuba's elMundo is the True Alternative To Gas Powered Vehicles.

When it comes to the regular Mundo, Yuba keeps it simple. It's an excellent cargo bike with a strong frame that can carry lots of weight with many of cargo and child-carrying options. This is a great option for people that enjoy getting that extra workout from their daily commute or when picking up the kids means only riding up a few hills. For many others, though, getting up steep hills (even with a lot of gears) or traveling long distances would make it impractical and inconvenient.

The elMundo is an answer to that problem. The elMundo's powerful Bionx electric assist system offers four levels of assist - 25%, 50%, 100%, and 300% to get you there faster and drier. The system's regenerative breaking system makes it possible to go up to 45 miles per charge, with a top speed of 20 mph.


The integrated rear rack is welded to the frame, resulting in unsurpassed cargo hauling ability, stiffness, and strength. Simple braze-ons allow for easy configuration and installation of Yuba accessories.

Driving this e-bike is a 350 watt gearless direct drive motor mounted to the rear wheel. The motor is designed for high torque applications and climbs well, and if you join in pedal assist mode it works even better. The real powerhouse on this bike is the battery pack which offers 48 volts of power and 8.8 amp hours of capacity. The pack locks into the frame, is removable and can be charged on or off the bike.

From Yuba Bikes: "On top of the bicycle's innate green design, the El Mundo will get you to almost any place a car will with a lot less pollution, carbon, and zero fuel. It's rechargeable battery lasts 20-37 miles — depending on usage and terrain — and costs 3-5 cents per charge.


It's the future: Electric bikes provide exercise, a relationship with the great outdoors, they save money, they're safe, they perform a bit like a car and a lot like a bicycle, they allow you to circumvent clogged arteries, and park almost anywhere. Oh, and there's no driver's license required"

"Simply Put, This Bike is A Blast!" New Tern Eclipse X20

The Ninja Pirate— The 2014 Tern Eclipse X20.

This would be the bicycle I gravitate toward the most. The wheels, the simplest way to dramatically improve the performance of any bike are in my opinion, flawless.  American Classic hubs are top notch, have been around for years and spin as if friction free.  Laced into them are .....  With forged bladed spokes these wheels are super light, super strong, and super easy to get rolling in a hurry!




The cockpit of the Eclipse X20 is simple and comfortable.  Perched atop the Physis handlepost, which is 3D forged making it practically bomb proof, is a flat Kinetic doulbe butted handlebar Ergon GS2 grips which are as comfortable as they are handsome.





Riding this bike really brings to mind "The joy is in the journey, regardless of destination".  For me, riding a bike is a mix of life's pleasures and the Eclipse taps into the part of me that is still 12 years old riding around the farm on my trusty BMX bike.  This bike takes me there and more.  As it's just as much fun but decidedly lighter and as cutting edge as a ceramic knife.  I promise you, if you ride this bike, you will love it.  If not, then you might be crazy.

3 Items That Will Improve Your Ride In SF

Photo Credit: Michael Macor, The Chronicle

 

All Bikes in San Francisco Need A Few Items That Aren't Part of the Bicycle.

 

1. Knog Blinder Road Headlight

I use this light for it's dual beam design which can be used with one light blinking and the other static. As a daily commuter it's paramount to have a blinking light. It's my belief that static lights are less noticeable than a bright blinking one. The blinder allows for this and also has a program for bright static beams for those few parts of town that are lowly lit such as Townsend St. or Golden Gate Park. Another great feature of this light is that it's USB rechargeable




2. Axiom Streamliner Rear Rack

After trying many racks over the course of my cycling life I have found the Streamliner to be the best for my uses. Rather than stack items on top of a rack or a basket, I am more inclined to use side mounted paniers and the Streamliner accommodates this method of carry best. It has a very narrow top, so narrow in fact that stacking anything on top of it is nearly impossible. It uses less material, making it lighter and keeps it within the lines of my bicycle. I love this rack!




3. Ortlieb Vario Backpack Pannier

Waterproof and with the ability to be converted into a pannier, it is simply the finest and most useful pack I've owned. It's strong and incredibly durable, making it a great value. It's design is based on functionality. For example, the structure allowing the bag to be used solely as a backpack is completely removable. There are no shoulder straps to tuck in anywhere, you simply detach the unit with it's quick release system, hang, the now pannier, on your rack and off you go! It's designed very deep. In fact, when stuffed full of "stuff" you may not even need to close the top. I discovered this design feature by accident after overloading it on a trip to the farmers market and being forced to ride home with bunches of kale and red chard sticking out the top of the bag like a bouquet of roses. Since first trying it on, I've used nothing else.

Hearing A Weird Noise When You Ride? Here Are 23 Solutions

Photo Credit: dabble.co

Got a Pinch Flat? Creaky Crankset? We Have Some Great Solutions For Common Issues

1. You fixed a puncture, and the new tube keeps going flat

If the holes in the tube are in the bottom, the rim strip may be out of position, allowing the tube to get cut by the spokes. If they're on top, there may be some small sharp object stuck in the tire. Find it by running your fingers lightly around the inside of the tire, then remove it.

2. A remounted tire won't sit right on the rim

Let the air out, wiggle the bad spot around, reinflate to about 30 psi, and roll the bad spot into place with your hands. By pushing the tire in toward the middle of the rim you will be able to see if any of the tube is poking out. When the tube is fully inside the tire, inflate as normal.

3. A patch won't stick to the glue on the tube

Apply more glue and let it dry completely, about five minutes (DO NOT BLOW ON THE GLUE) When you apply the patch, avoid touching its sticky side with your fingers.

4. A creaking sound from the wheels

A spoke may have loosened. If tension is uniform, the sound might be caused by a slight motion of the spokes against each other where they cross. Lightly lube this junction, wiping off the excess.

5. A creaking sound when you pedal

Tighten the crankarm bolts. If the arm still creaks, remove it, apply a trace of grease to the spindle, and reinstall the arm.

6. The large chainring flexes, and the chain rubs against the front derailleur cage.

Check for loose chainring bolts

7. You have removed the chainrings to clean the crankset, but now the front derailleur doesn't shift right. 

You may have installed a chainring backward. Remove the rings and put them on correctly. Usually, the crankarm bolts fit into indentations on the chainrings. Sight from above too, to make sure there's even spacing between the rings.

8. While trying to remove or adjust a crankarm you stripped the threads- Now you can't remove it

Ride your bike around the block a few times. The crankarm will loosen and you'll be able to pull it off.

9. Shifter housing rubs the frame, wearing a spot in the frame

Put clear tape beneath the housings where they rub.

10. Noisy sloppy shifting can't be remedied by rear derailleur adjustment

The cassette lockring might be loose, allowing the cogs to move slightly and rattle around on the hub. You need a special tool to tighten the lockring fully, but you can spin it tight enough with your fingers to ride safely home or to a stop.

11. The cog cassette is getting rusty

A little rust won't damage the cogs quickly, so it's not a major concern. Usually, using a little more lube will prevent additional rust, and riding will cause the chain to wear away the rust while you're pedaling.

12. In certain gears, pedaling cause loud skipping

There may be debris between the cogs. If you can see mud, grass, leaves, twigs, or any sort of foreign matter trapped between cogs, dig it out. It's probably keeping the chain from settling all the way down onto the cog to achieve a proper mesh. If there's no debris, a cog is probably worn out. Most often this is a sign that the chain and cassette will have to be replaced.

13. Front derailleur won't shift precisely to a chainring

Check that the cage is parallel to the chainrings (when viewed from above), and loosen and reposition the derailleur if necessary. If it's parallel, you probably need to adjust the high- and low-limit screws, best done by a shop or experienced amateur mechanic.

14. The rear derailleur makes a constant squeaking noise

The pulleys are dry and need lubrication. Drip some light lube on the sides, then wipe off the excess.

15. Braking feels mushy, even though the pads aren't worn out

The cable probably stretched. Dial out the brake-adjuster barrel (found either on the caliper or on the housing closer to the lever) by turning it counterclockwise until the pads are close enough to the rim to make the braking action feel as tight as you want.

16. Braking feels grabby

You probably have a ding or dent in the rim. This hits the pad every revolution, causing the unnerving situation. Bring your bike into Bumstead's. We'll fix it for you.

17. One pad drags against the rim or stays significantly closer to the rim than the other

Before messing with the brakes, open the quick-release on the wheel, recenter the wheel in the frame and see if that fixes the problem. (This is the most common solution.) If the wheel is centered but a pad still rubs, you need to recenter the brake. On most modern brakesets this is done by turning a small adjustment screw found somewhere on the side or top of the caliper. (There may be one screw on each side, as well.) Turn the screw or screws in small increments, watching to see how this affects the pad position. If you center the brake and the wheel, and a pad still drags on the rim, it probably wore unevenly from being misadjusted; sand the pads flat and recenter everything. 

18. With each pedal stroke you hear a click coming from the saddle

The pedal may have loosened. Tighten it.

19. Squealing Brakes

Wipe the rim to remove any oil or cleaning reside. If this doesn't work, scuff the pads with sandpaper or a file. Still noisy? The pads need to be loosened, then toed in; an adjustment that makes the front portion touch the rim before the back- an easy fix for a shop, a tortuous process for a first timer.

20. Creaking Saddle

Dip a tiny amount of oil around the rails where they enter the saddle, and into the clamp where it grips the rails. Heritage purists take note: Leather saddles sometimes creak the same way that fine leather shoes can. There's not much you can do about this.

21. You can never remember which way to turn the pedals

Treat the right-side pedal normally — righty-tighty, lefty-loosey. The left side pedal has reverse threads (to keep it from unscrewing during pedaling). If that's confusing, just remember this simple phrase: Back off. This can remind you that, with the wrench engaged above the pedal, you ALWAYS turn toward the back of the bike to remove the pedal. 

22. You installed a pedal into the wrong crankarm - The left pedal into the right arm or vice versa

You can remove the pedal, but the crankarm will have to be replaced; its threads are softer than the pedal's and are now stripped out. ALWAYS check the pedals before installing. There is usually an R for right or an L for left stamped onto the axle. 

23. You pulled apart your headset to regrease it, and now the headset feels tight no matter how you adjust it

The bearing retainers are probably in upside down.

Current Bike Too Cumbersome and Bulky? The Dahon Curve D3 Has Your Solution

Stylish, Compact and Smooth, The Curve D3 Fits In To Most Places — and Budgets

The Curve comes fully loaded for commuting in the city. It comes with fenders in the front and the back, mudflaps for keeping your clothes, bags and gear clean. It also comes with a rack and bungee cord strap on the back. A bit smaller than other models, but it is extremely adjustable. The seat post and handlebar adjust to accommodate riders from about 4'6" to 6'2".


Also take a look at our previous post about the Dahon D7 - Warm Planet's Top-Selling folding bike.

 Folding this bike is a breeze via three main hinges. The first is at the middle of the handlebars, the second is at the junction of the handlebar and the frame, and the third is just past the middle of the frame near the seat post. Once you have folded and locked those into place, the telescopic seat post fits all the way down close to the frame, and the pedals fold in for an ultra sleek and convenient method of carrying and transporting your bike.



The Curve D3 is especially small and compact when compared to some of the 20" models, resulting from its 16" wheels. Great if you need to take the train or BART or if you just don't have much space in your home or office for your bike.

Comes with Shwalbe Big Apple tires — wide balloon tires that absorb lots of shock and are lined with a tough Kevlar lining, making the bike virtually flat proof.

Its simple 3-speed shifting is intuitive, covering a range that is more tha sufficient for city riding. Bright red in color, the Curve is definitely visible to the surrounding traffic AND to the throng of infatuated onlookers.

Comes in White Too!

From Dahon.com: Customers rave about the stylish and delightfully smooth handling of the Curve D3, one of our most popular bikes. It's the perfect bike for an easy commute or as a secondary mode of transportation stashed in a car. With its impressively small folded package, it's easy to take two for a weekend getaway!

Come in to Warm Planet Bicycles today to see the Curve D3 as well as many more great folding bikes from DAHON, Bike Friday, Montague, and Tern.

Where Do You Go to Buy a Tern Node D8 in San Francisco?

Do Everything Folding Bike at a Price You Can Afford

If you could design perfect urban transport for San Francisco, you’d want a bicycle that rode and handled like the best city bikes on the market. You'd want that bike with a reasonable price that could fold in a flash so you could take it on any city bus or stash it in any cafe coat closet. That’s the Node D8, a new kind of bike that’s designed to get you around and get your stuff done.

Consider the following design and function features when you get ready for a folding bike.

 

 

N-Fold Technology

The Faster Fold
Folding bicycle design hasn’t changed much in decades. N-Fold Technology is a small but important change that results in a faster, and more compact fold. N-Fold Technology includes new frame and handlepost geometries and spins the front wheel by 180 degrees before the central fold, resulting in a package 40 mm (1.5”) shorter. Using N-Fold technology, our Eclipse and Castro bikes are only very slightly larger than the typical small wheel folding bicycle. Bicycles with N-Fold technology can also be folded – easily – in less than ten seconds.

OCL Joint

Stronger, Better, State of the Art
The OCL Joint is a new reference in folding frame technology. It includes two new patents and everything we know about making the safest, strongest, and most durable frame joint.

• Taller, Stronger, Stiffer — Making the hinge taller and moving the pivoting surfaces outward from the center axis more than doubles overall strength and stiffness and it’s a difference you’ll feel from your very first ride.

Continue reading


*******

 

 

DoubleTruss

3-D = Stronger
Folding bikes have a sometimes deserved reputation for flexy frames. All Tern frames feature patented DoubleTruss technology which turns the rear half of the frame into a three dimensional truss so that it’s much more resistant to torsional forces. That equals increased stiffness and much better power transfer from the pedals to the rear wheel.
Continue reading


*******

 

 

Physis 3D Handlepost

3D-Forged = Even Stronger, Stiffer, Better Ride
The Physis has quickly built a reputation as the stiffest folding handlepost on the market, but the Physis 3D takes it up a notch with 3D forging technology. The Physis 3D is forged from a single, solid block of aluminum. Only a small handful of factories around the world can 3D forge such a complicated, large piece. Welds are eliminated and material distribution optimized for strength. The result is a handlepost that is 2 1/2 times as strong as the original benchmark on rigorous EN tests. Plus, it doesn’t look half bad either.

********

 

 

Neos Rear Derailleur

Designed for Small Wheels
The Neos derailleur was developed to solve issues specific to small wheeled folding bicycles, specifically, ground clearance of the derailleur cage, and protrusion of the derailleur body from the chainstay, making it susceptible to damage. Working with Suntour, we developed the Neos family of derailleurs. The low-profile design mounts directly to the chain stay with the body of the derailleur tucked underneath, protected from damage. The ultra-short cage doubles the amount of ground clearance and produces lightning fast, precise shifts.

*******

 

 

Luggage Socket

Carry More Stuff
When you need to carry more stuff on your bike, just plug the optional Luggage Truss into the Luggage Socket that’s welded to the head tube of every Tern bike. The Luggage Truss works with any bag, basket, or rack with a KLICKfix adapter. The benefit of a frame mounted luggage system (as opposed to fork or handlebar mounted) is that it doesn’t adversely affect steering. Available Tern accessories include: Kanga Rack, Tour Bag, and CarryAll Basket.

Fast, Light and Foldable Bike Works Perfect in San Francisco

The Pirate Ninja Eclipse X20 from Tern Folding Bikes

At Warm Planet Bikes we are always on the lookout for a standout bike.  And in this case we shouted bike ahoy!! Tern seems to be smuggling just the right gear onto the San Francisco shoreline.

This one is more than fast and light enough to launch a brigand’s attack on an unsuspecting roadie, yet stealthy enough to slip – folded and shrouded – into the subway unnoticed. The Eclipse X20 is as lithe and sleek as a ninja. But with its super-wide 25-107” gear range and lightning-fast Kinetix Pro wheels it’s got pirate-worthy swagger that demands attention. Slice to the heart of San Francisco – whether you prefer a katana, a cutlass, or both. A winning combination if there ever was one. Debate settled.

Consider these benefits:

Smooth TIG Welding

********


Beauty Meets Function

The normal TIG welding process for aluminum bicycle frames is done by hand and involves the welder laying down a series of small, overlapping beads covering the two parts to be joined. The better the welder, the more uniform the beads. In the smooth TIG process, the welder makes a “double pass”, laying down a second layer of beads on top of the first. These beads are then sanded down by hand in an intensive process that requires extreme care. Done properly, the frame is strengthened because the possibility of stress risers is reduced. And the result is a very smooth weld joining the two tubes.

Physis 3D Handlepost

3D-Forged = Even Stronger, Stiffer, Better Ride

The Physis has quickly built a reputation as the stiffest folding handlepost on the market, but the Physis 3D takes it up a notch with 3D forging technology. The Physis 3D is forged from a single, solid block of aluminum. Only a small handful of factories around the world can 3D forge such a complicated, large piece. Welds are eliminated and material distribution optimized for strength. The result is a handlepost that is 2 1/2 times as strong as the original benchmark on rigorous EN tests. Plus, it doesn’t look half bad either.

Syntace VRO 47 Stem

Fitted to You

The VRO 47 stem gives you all-important adjustability so you can fine-tune your riding position for speed or comfort. The stem is 47 mm long (14 mm longer than the standard VRO) and it’ll go anywhere from -45 degrees to +90 degrees or even backwards if you want to reduce the reach. And it exceeds Syntace’s brutal in-house test procedures for downhill gear. Custom-built for Tern.
Syntace is a German company renowned for their incredibly light but amazingly strong stems and bars.

Ergon GS2 Leichtbau Grips

Grab Hold

If you’ve never ridden with bar ends, you owe it to yourself to give ’em a try. Stand up and climb or just haul ass, the extra torque and control is like nothing you’ve experienced before. GS2 grips are bigger with softer and more generous wings to reduce pressure on your ulnar nerve and ease wrist strain. The soft kraton rubber main body gives just enough while a textured rubber insert on top dissipates jolts and vibration.

Stasis Seatpost by Syntace

 Ultra-light, ultra-tough
 

The Syntace P6 is one of the strongest and precisely engineered seatposts on the market. We wanted the best so we worked with Syntace to develop a 580 mm seat post with a variation of their 3D cold-forged P6 clamp. Made from ultra-light 7075 aluminum and hard-anodized (black color option) for scratch resistance. ERS technology delivers loads of fore/aft adjustment for the saddle: you can run the saddle forward for zero offset stiffness, or all the way back like an offset seatpost. Two bolt micro adjust for infinite angle adjustment. Continue reading

Kinetix Pro 507 Wheel

Light and Fast

The Kinetix Pro 507 wheels represent everything we know about making the best possible wheels, costs be damned. We start with the best ingredients: custom ultra-light American Classic hubs rolling on stainless steel bearings; Sapim bladed spokes custom-forged to our specific lengths; Niobium-alloy rims that are light but incredibly strong. A master wheel-builder then hand laces each wheel to incredibly strict standards as defined by the man, Rolf Dietrich. Each wheel is laced and trued, de-stressed with our custom Black Box, trued again, and de-stressed, before the final truing.

Schwalbe Kojak Tires with RaceGuard Puncture Protection

Liven Up Your Ride

We’re pretty sure the folks at Schwalbe were thinking ‘70s American TV when they named this tire because, yes, Kojaks are bald and more than a little sassy. Comfortable and surprisingly fast, we like the SpeedGrip multilevel dual compound for high levels of grip and low levels of rolling resistance. And there’s the proven RaceGuard protection belt, developed specially with racing in mind. Who loves ya baby? Kojak does. Ol’ Telly would be proud.

Magnetix 2.0

Better Together
Our first-generation Magnetix were good and sticky. They did a fine job of holding a folded bike together. But in some situations – like carrying a bike up and down stairs – the magnets just weren’t strong enough. Our new Magnetix 2.0 increases the strength of the magnets by 300% to keep your bike folded even when being jostled and moved about. The previous Magnetix had a pull force of 4-5 Kgf. The improved version clocks in at 10-15 Kgf. We like the new Magnetix 2.0 a ton and think you will too.

Tern Tail Masked Paint

 Super-fine Details

Getting this finish just right needed a LOT of work with our paint factory. It basically involves incredibly meticulous hand-masking to achieve the final result. With the silver/black finish, we hand-polish the aluminum frame to a mirror finish and then follow that with hand-masked black paint. Detail: the shape of a Tern’s tail is echoed in the paint masking.
