Couldn't Wait

I'm still waiting on some parts to complete my electrick trike conversion but couldn't stand it any longer and hooked it up yesterday in the friction drive mode. I had tried this a little with a brushless drive that was too small and it worked at low speed but was slipping a lot. I added more bungees and then when I tried to roll on throttle it sounded like the drive was out of sync with the motor. I tried it at several different speeds with the same effect... finally added a bunch of throttle and it promptly smoked the drive. Luckily didnt smoke the battery... it had melted one of the power solder connections to the drive which saved the battery. 

After reading some posts about others using a friction drive arrangement I decided to try it again. I didn't smoke anything this time but I did manage to grind a little off the OD of the tire. I could have added more bungees but thought I was already pushing the limit on how much of a side load I wanted to have that far out from the bearings.

I got the new hub and rim and I've made an adapter to mount a chain ring on the brake rotor mount. Still waiting for spokes for the wheel so tried this one more would do about 17 miles an hour on level ground. It is a 245 KV motor and I was running it on 22 volts.I don't believe I'll have any problem getting 25+  miles an hour out of it on 44 volts.
