Hi, Been lurking for a while and considering building an eBike for some time now.
Spent some time looking at all the various motors etc trying to make my mind up what I want.
I have been using the simulator here which I found very useful: http://www.ebikes.ca/tools/simulator.html
My requirements are this:
45km/h (28mph) on flat ground cruising speed, I will spend most of my time at this speed as I intend on MSVA testing this bike and registering it as a Moped.
Reasonable hill climbing performance. Most of my riding will be on relatively flat terrain but on longer touring rides I could encounter hills upto around 15% (1:7)
Weight of bike and myself will be about 140kg.
I am looking for a range of about 240km/150 miles in ideal conditions on flat terrain cruising at around 40km/h
I would really like regen to help me maintain the 45km/h speed limit on downhills and share some of the braking load from my friction brakes (current thoughts for the friction brakes is 2x 90mm drum brakes front and a basic disc brake at the rear which will mainly be there to keep the lawmakers happy (Rear brake is required for MSVA).
My current thoughts for the motor is the 9c 3004 built into a 20" wheel. I have also considered the Crystalyte hs3548 motor but I like the 9c as it used a cassette hub as opposed to a screw-on block.
My current thoughts for the battery is 16 CALB CA-40ah LIFEPO4 cells in series to give 51v nominal, ~2Kwh. I have also considered the A123 20ah pouch cells in 2p16s which would be lighter but seem to be hard to find these days and seem much more expensive than the CALB. To manage the battery I am considering the orion-bms junior http://www.orionbms.com/downloads/documents/orionbms_jr_specifications.pdf
For a controller, currently considering the GRINFINEON - C3635-NC http://www.ebikes.ca/c3635-nc.html
