Hello,

I'm going to be teaching a physics-based workshop for high school students. They'll learn about the physics of bicycles, and during the month they will be converting their bicycles into electric bicycles.

I'm posting this as an open call for suggestions on which kit I should choose. The easiest, slickest kits on the market are way out of our budget, so really I'm looking for the cheapest kit available that would be worth pursuing (not the absolute cheapest!). As this is a hands-on workshop, assembly steps are not an issue; in fact, the more work involved, the better opportunity for instruction (i.e. building a wheel up from a hub rather than buying a complete wheel). Friction drives are totally an option too, if it helps get the price down. We're more interested in the hands-on opportunity than the power of the end product

Also, if it makes sense to buy individual components instead of kits, I'm game for that as well.

For reference, we should have about 5-10 students in the first workshop, so any info on companies that will sell discounted in quantity (or to a nonprofit) would be great.

Thanks,
