This has been a very successful conversion. This is my 9th build and has already provided me with over 200 miles of excitement in the last month.
Here is a video of the bike: http://www.youtube.com/watch?v=NoZTnnfpeZU
I purchased a used kona kikapu, installed a new used fork from one of my old dh bikes, and a 9 continents 9x7 rear hub motor. and installed a disk brake adapter from bicycle designer which works surprisingly well, I couldn't fit an 8'' rotor and a 6'' just barely fit because of the width of the hub motor. I didn't have rim brake tabs so v-brakes were not an option.
I used 2 ping 36 volt 15 amp/hr packs, using galvanized steel flashing and rivets we built boxes to hold and protect the batteries, switches, ports, and connectors:
I used an original e-crazyman 72v 30 amp controller from knuckles which somehow is still working One morning I tried to get the bike powered up after a long, torturous ride the evening before and no go. After detailed inspection I found some loose connections in the controller where the heat must have melted the solder here:
Everything has been working great. the bike runs smooth, Although I prefer the power off the line of my 60v 50 amp stinky, this bike is very smooth and the nine continents hub handles the overvolting with little reluctance. It gets hot after 10 miles or so but never stops. this things a thrill. it may not have the same top speed as my freinds quantya's but with 1/8th the cost, a longer range, no insurance, no registration, easy parking, easy loading, cheaper parts, and you can carry it over shallow rivers :wink:
Questions, Comments, Advice, Thanks!
