Right on. Thanks, guys!

Hey guys, ballpark question here: If I were to hook up a bicycle crankset to a generator, and connect the generator directly to a hub motor such that human pedaling would (almost) directly power the hub, what kind of efficiency loss am I looking at? I realize that I would be paying an...

Dude, I work in software. Solutions... Solutions To Imagined Problems You Don't Really Have You touched a nerve with me on this one. Drives me up the wall.

Hey guys, I've just recently finished my second bamboo bike. This one is the world's first "fat bike" made of bamboo - like a Surly Pugsley if you're familiar with snow / sand biking. Check it: http://dillerdesign.com/random/bike/fat_bamboo_v1/beauty_and_the_beast.jpg Here's a very terse build...

Been a while since I've visited E-S, thought I'd take a peek around again... This thread caught my eye, since I live in MN. DUDE. Pogies. Get some @$*#ing pogies. http://barmitts.com/ I can wear regular summer full finger cycling gloves down to about +10F ... colder than that, you'll need...

I should have clarified that this would be for a human power only bike, and I'm posting here for the expertise available on this forum. I plan on making an electric fat tire bike, but not this one. I've run some DC-DC converters on my road e-bike, worked really well.

The studs are from a French company called UgiGrip. They're 11mm long. I wish I could have gotten my hands on some 10mm length studs instead. Basically you can get tungsten tipped studs in the US, but they're expensive, something like $1 per stud! These, I got off Ebay, 1,000 count for $42...

Just sharing some pics of some carbide tipped studs that I added to my Surly Larry fat tires: http://dillerdesign.com/random/bike/studded_Larry_tires/

Hey guys! Been a while since I've posted here. I have a problem that is unique to this forum, but not all that unique in general. I wish to use a low drag generator hub like the very nice Shmidt SON hubs, but I can't. Those hubs have an O.L.D. of 100mm, very typical of a fork dropout. The...

Hehe. TWO DOLLARS!! So far so good.

I haven't posted here in a while, because I haven't e-biked in a while, been too busy off roading with my new-used Surly Pugsley (which I might electrify later this winter). I must say getting back on an e-bike after having been without gave me the EV grin all over again :D It's fall, which...

Fedex, UPS, and USPS all tell me that my lame civilian self can't ship a battery though them. What gives? How does one sell and ship a used e-bike battery?

This. Basically because cyclists are often off the side of the road, and are not anywhere near as wide as a car. I live in a suburb and I have to be careful when using ped paths and cross walks. There are some intersections where a right hand turn with a red light is treated as "stoptional"...

So is this something other than a Gruber Assist drive?

Having experience with both Power Grips and clipless pedals (I call them click-in pedals), I will say this: Power Grips are nice because they're cheap, simple, don't require special shoes, and keep your foot from falling off while biking off road. You can pull up on them if they're fit snugly...
