I received my parts from cell_man this past week and got a chance to assemble my ebike yesterday (Aug. 6th). I won't go into a lot of detail except the basics and to share some pictures.
I have the choice of two donor bikes, a 2005 Raleigh C-40 with a 17 1/2 men's frame and a 2008 Diamondback Century flatbar road bike. Both bikes have aluminum forks, with a suspension fork on the Raleigh, but since I'm using a rear motor, that doesn't matter.
My kit consists of a 1000W 8T, geared hub-motor laced into a 700C wheel with an 11/32 freewheel. That's couple thru the controller to a 48V 11.5Ah A123 triangular battery pack in a nylon frame bag, tied via the harness to a thumb-throttle with a separate selector switch and brake cut-off. Total cost to Seattle from Shanghai (with shipping) was about $1250 clams. I chose SAL and though somewhat slow, everything arrived safely and was packed very well. Paul does a great job with the kits.
First pic, showing the battery pack fit into the frame triangle:
The controller fitted under the rear rack:
Wiring:
Throttle set up:
Tidying up:
Finished set up:
All in all, a very good build. Difficult parts were dealing with a leak in the tube (I've purchased a replacement since...) and getting the throttle integrated with the shifter and brake. I will most likely replace the thumb-throttle with a twist-throttle as soon as cell_man gets me a price and shipping cost. I had to relieve some of the material on the shifter to get it all to fit. A lot of fussing-around...
I took the bike on a short 8-mile ride today on a dedicated trail. In my top gear (24) on Level 1 I was able to easily peddle to 21 MPH. I tried Level 2 and it shot up to 28 MPH! I was afraid to try Level 3, as there were too many people on the trail. As it was, peddling in Level 1 was a good match for a paved trail on a Sunday afternoon.
The motor is very quiet. I could barely hear the gears. The way the bike is set up and wired, it would be hard to tell it was electric unless one looked closely; the perfect stealth bike.
The suspension absorbs the bumps well and the bike as a whole rides well. I'm REALLY glad I paid the extra $$$ for the triangular pack and nylon bag. It gets the weight of the battery centered and the cG much lower than on the back rack. The build og the A123 cell-pack is superb!
I *may* tear everything off and try it on the Diamondback just for fun, but this is working well for right now. My only criticism of the kit is not shut-off switch, but it's easy enough to unplug the wires, and actually, that may be a safer way to go anyway.
Cell_man does a good job with the product, though there were no instructions, but setup is pretty straight-forward. Paul is VERY responsive and has been wonderful, patiently answering my many questions. Many, many kudos to him and his suppliers. I have a far faster bike than the ready-built bikes I was looking at, with more umph and more range.
Another ear-to-ear e-grin!
