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." —

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:

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.
