feasibility of pedal-to-generator-to-motor chainless bike?
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 efficiency pen...

Re: Wooden bicycles, lots of pics
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 b...

Re: DIY light hub generator examples?
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.

Re: Studded bike tires, selection and first ride impressions
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. While th...

DIY light hub generator examples?
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 bike I'm ...

Let's see some e-bikes doing some work!
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 means c...

Re: bike crash video
The second car that actually hit the dude, was very very likely having his view of the oncoming bike blocked by the car in front. Something to remember. If you take the lane to cross at a big light, most likely you are behind a car, and look like a space in the traffic to the cars across the inters...

Re: Clipless pedals and efficiency
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 to a g...

Re: New MagicShine Triple Headlights!
Did you hook this light into your main battery pack, or are you running it off of the small rechargables? I actually sold the unit to a friend, I was running off the little rechargeable pack they come with. I've since moved onto a pair of the older model, the 900 lumen (though it's more like 700), ...

Re: Currently a hub user. Which way should I go?
The little cutie isn't going to have enough power to get you thru the snow, except at near walking speeds, which may not be a bad idea in the snow and ice. Right. I wish I had two throttle modes. One "normal" and one "tractor". There are some modes of ice that are dangerous even...

At its top speed - 16mph / flat ground / no wind - it consumes 200 to 250W.

Currently a hub user. Which way should I go?
I ride on a single speed Cute 128 rear hub with an Infineon controller. It tops out at 16 mph and I worry about driving it hard up hills (and, I wish it had more torque for more serious hill climbing ability). I want to build another e-bike. This will be a snow e-bike, I want it trail worthy in Nove...
