hi all
now that my bmc mountainbike with mac hub motor is finished, it's time for a new project.
i saw some bmx style conversion, and thought i could use my beautiful klein mantra which i bought 15 years ago (and still looks like brand new - i took great care) and modify that. i'd like to do the following:
.) 9c 2805 hub motor in a 20" rim -> crystalyte 3540 and alienation delinquent rims
.) maxxis hookworm tires -> pirelli ml75
.) infineon eb312 controller -> check
.) ~20s1p a123 pouch cells -> 24s1p a123
.) peli case 1300 mounted under the handle bars -> too small -> chose explorer 2717 at the handlebar
.) disk brakes front (already installed) and rear -> avid elixir3 and 200mm disc
.) cycle analyst -> v3
what do you think?
this is the bike as it looks like now. i love the look, but it always was a bit too small/short for me, and riding in the hills made the front wheel lift all the time.
i'm still a bit woried how to mount torque plates/arms, as those dropouts look really thin and weak
as i want to reach 40mi~60km/h i would have to feed it 2.5kw.
.) i'm also still unsure which kind of throttle to use. what do you prefer? half grip? thumb throttle?
.) should i use all 21 gears? or just the three front gears OR the seven in the back?
cheers izeman
update 20121214:
i bought a crystalyte 3840 and 12fet infineon controller.
i also switched from hookworms to pirelli ml75 2.75
update 20130201:
this is what it looks like now. found out that the controller is sensorless, so i ordered a new sensored.
update 20130302:
frame welded
update 20130321:
ready to ride, at least for a test ride. frame still needs to be painted, and some other stuff is to be done
update 20130416:
almost done, some cosmetics to do, but it's done:
update 20130527:
latest addition is a PAS, and a nice rear led light.
bought a new fork. 120mm air/air. much better ride, and better looking as well
