Took like 30 min to adjust them properly now they stop like a champ. I think i need to get new bearings in my crank. There is a little play. Ill ride these out until they die and get a new crank arm with larger rings. Other than that I lubed and tweak my shifters they shift perfectly. Back wheel has a hop in it... Its not the rim its the tire. It needs to be reseated or when I get some street slicks that should fix that. But I kinda like the tires that are almost hybrid tires. The tread is not as agressive as full mountain bike tires but they arent street either. Ill have to check them out. I removed the disk brake calipers from the fork but i could get all the screws out of the rotor on the rim. I used the right size torx bit but it stripped all but two screws... I trashed the rim kept the washers that fit into the bowl on the drop outs to make for an even flush mount. Im just cleaning up the bike and waiting for my motor to get here. I didnt want to get a traditional rack that mounted down to the axel on the rear wheel. I think Im just going to find a sturdy seatpost rack and a mtx trunk bag. They should hold 20-30lbs

Yeah that was me. I don't recommend adding the experience to the list of things to do before you die. If you do, best put it last on the list...
Mine was non-regen braking - same deal as regen but was dissipating the energy into a coil of wire rather than back into the batteries. I was using it in the absence of front brakes because I couldnt fit discs to the GM and my forks had no v brake mounts. Seeing as you've already sorted front brakes I'd highly recommend against it - not worth the risk on front hub motors for such minimal regen gains.
Re: the watts up meter, remember they're only rated to 60v and you'll promptly kill it if you try and put higher voltage into it.
icecube57 wrote:Yesterday was a fun day.. Today just had a host of problems. I had some serious wiring issues. The connectors I were temporarily using kept burning up. They were fine under light load but when I went for more than 20 secs WOT the power would cut out... Not completely. The pack voltage lights still worked but there was such a volt drop at the connectors the controller LVC kicked in under load. I was going to try for a long distance drive but with those problems I didnt even make it out my apartment complex. I worked the past hour re doing all the wiring. Seems to be working fine now. Even under stall. I also took the time to tune my gears. They were way out of check. The gear number shown wasnt the actual gear that it was in. I finally got everything lined up correctly. Everything shifting correctly according to the numbers on the shifter. The front derailer alignment was way off. It kept causing the chain to pop off. I keep seeing why this bike was discounted. I did a bike only ride just now. Shifting smoothly. Got a new pump. Pumped my tires up to 60psi. Ride wasnt harsh. The suspension took alot out of stiffness you get in hard tail bikes with that high psi setups. I tweaked my seatpost rack. It kept swiveling even when tighen down all the way. I ended up taking my old handlebar grip and putting around the seat post and then put the seat post rack on top of that and tightened it down. No more swivel. Moved the controller from the along the top tube and attached it with heavy duty zip ties to the seatpost rack. It doesnt interefer with the mounting of my battery bag on the rack. My battery is sitting at 60v floating charge on the charger. 58v after 1hr sitting off charger. After applying a load it drops to 54 v. I havent even been able to do a 5% discharge yet. With all the work Ive done today tommorrow is defintely a good test day. I feel it. Im still waiting on my Watts Up meter.... Still trying to figure out how to mount it too.
Im also about to get these torque arms on ebay. http://cgi.ebay.com/E-Bike-Torque-Arm-E ... .m20.l1116
Anyone ever use them?
