From some folks on endless sphere that currently have hub motors....they're now converts.
I also found a US based company importing and selling them: http://lectriccycles.com/
I'm not impressed by the fat bikes he has (or the cost), but the basic unit seems inexpensive enough for me to possibly make the jump to owning a system.
Thoughts? Reivews from someone on BikeForums?
I used the 350W from lectriccycles to convert my 2001 Trek 7700 cross bike. I ordered the 36v 14.5AH battery. The conversion went pretty well. I tore down the Trek to pretty much bare frame with just the existing fork and rear v-brake before I started. I kept the 9 speed XT rear derailleur but removed the front derailleur entirely. I switched out the front v-brake for a disc. Had to get a new front wheel to do that.
The Trek had integrated Shimano brake/shift levers. I had to remove them because the Bafang came with its own brake levers (incorporating the motor cutoff switches), and I no longer needed a front shift anyhow. I got a SRAM 9 speed twist shift for the rear derailleur on Amazon for $20.
Installing the motor: I had to buy a few tools to remove the cranks and bottom bracket. In hindsight it would have been cheaper to take it to the local bike shop and have them do that. 15 minutes work for them would be pretty cheap. Other common tools I already had such as allen wrenches, screwdrivers, chain tool, cable cutters, etc. You will need a spanner wrench such as Parks HCW-5 lock ring spanner to fasten the motor to your frame.
The kit came with NO installation instruction other than an exploded view of the parts showing how it fit on a bike. There is a very helpful Youtube at http://www.youtube.com/watch?v=jf6BMf28ats
There is a pdf manual explaining how to use the LCD handlebar control to program the system. I finished the install on 2/13/2014. I'm in Denver and have had limited chances to ride due to weather, but have done 3 rides, 6 miles, 26 miles and 13 miles. I'm not a speed demon or a dirt bike guy. I ride for recreation and fitness. I'm 75 years old and the hills were getting steeper and longer every year. The e-bike has changed that. Two of the three rides I've done so far are rides that I hadn't done for several years. Now a piece of cake.
The LCD panel never showed any battery discharge at all - stayed on 4 bars even on the 26 mile ride. Battery full charge took about 2.5 hrs after that ride. Oh, and this motor is QUIET. The only noise I heard was normal chain and crank noise, meaning nearly silent. So far, so good.
