Thanks guys for the encouragement, I appreciate that.
I designed this bike on paper first, every part of it, then made templates for everything and hung them on the bike before constructing it. Yes I did all the machining myself, the only parts I did not make are things like miter gears, sprockets, bearings, chains things like that. I know some of the spacing around things looks a little too close but it is only the photos, everything has quite adequate clearances.
I have designed a friction drive electric bike already and all I can say is it sucked, and it was a very nice design. I rode it twice, about 5 miles worth, and it worked so bad and made so much noise it was embarrassing so I tore it apart and built the bike you see, it cost me a year but well worth it for the new bike. There are so many problems with a friction drive I don't have time to talk about it, chain drive I have found is the best way to go other then hub motors. I call this my second e-bike but it is really my third e-bike, 2 no longer exists, one learns a lot building these things. Anyway I do not recommend a friction drive for many and varied reasons.
Each side of the transmission can be removed to get at things inside bearings, gears, sprockets etc. It has primary chain adjustment by 2 means, a delrin shoe inside and adjustment of the rear bearing, there is a secondary chain tensioner in there as well, all built by me. The tires are 65 psi Kevlar knobbies for good traction, it has speedometer, odometer etc.. All the wiring is in-cased in pvc coated fiberglass tubing, all the messy wiring connections are done inside the controller box, which I ended up swapping location of the LED and kill switch on, to get the kill switch in a better location. I made the road pegs at the rear wheel as well as all the other metal work you see. All I need now are a couple eagle decals for the sides of the battery covers and a day with some semi-crome polish.
