Here, 5 mile range ebikeThis morning, one of those Greg LeMond wanna be guys all decked out in spandex and seated on a carbon fiber racing type bike was behind me at a stop light. I was on my $600 250W eBike. I smoked him on the acceleration, but his higher gearing meant that he passed me pretty quickly after 20MPH was reached.
This is not acceptable! I'm still gonna retain the current eBike because it's great for hauling stuff, but the fun of furiously pedaling and going as fast as I could was a blast.
So how can I build a fast eBike using a kit that will get me 30 to 40 mph quickly for $600? I don't need a ton of range, just something to get me 5 or 10 miles while I troll for yuppies on bikes. Do I need 1000w of power, or 1500? I figure a non geared hub motor on the back would be in that price range w/ a battery. Has anyone built such a bike? Is this the best way to go, or is a geared motor better? I'm a little concerned about a big hub motor fitting into the chain stays back there on a donor bike, along w/ getting the freewheel or cassette to work.
Going to a front hub motor would simplify everything enormously, but is that a good idea w/ a powerful motor? I'm thinking the handling would be sub optimal, and if you powered it on too much in a curve, watch out.
