I have a bakfiets.nl cargo trike and I'd like to fit it with an electric assist.
I'm looking for something that will be road legal in the UK (if at all possible), and a top speed of 15mph is fine.
My daily commute is around 6 miles each way and I'd like to be able to do that at around 12-15mph, so a range around the 20 mile mark under full load would be good. The route is mostly flat with a couple of hills that are steep but relatively short (if I'm in an energetic mood I can power up them without changing gear). The big issue is weather. I need something that is or can be protected against driving rain and 70mph winds and will still give me a boost (albeit not to 15mph!) even in those conditions. I'd like it to be able to help me to at least 6-8mph in those conditions rather than the 3-4mph I manage unassisted.
As I have a Shimano Nexus 8 hub gear on my rear wheel I want to fit a pair of front hub motors, preferably slaved to a single throttle, controller and/or battery. All my wheels currently have disc brakes.
I weigh in at around 180lbs/85kg, and the trike weighs around 40kg. I'm not against lead acid rather than lithium batteries, I'm already carrying a lot of weight so it won't make much difference. If I can get something that will give me a decent amount of low speed torque that would be nice, as I occasionally carry heavy loads.
I'd like to do all this under GBP900, but I'll stretch all the way up to GBP1200 and maybe beyond if needs be.
I realise I'm probably trying to get a unicorn here but I'd appreciate any advice you can offer.
EDIT: d'oh, forgot to mention that front wheels are 20" each, in 100mm drop outs.
