Hello, this seems a nice place, I did some reading and now it is time for me to ask for some friendly (if possible) advice
I am a 105kg rider on a 12kg trekking bike with (occasionally) 30kg of luggage. The bike has 28" wheels and I would very much like to add a bit of electric assistance. I am not after "stealth electric moped" - I would very much like to rely on pedal power but have some support for the longer commute I am facing, being very much out of practice.
MOTOR PONDERING
Having read up on the available information here and elsewhere I am pretty certain that a hub motor with planetary gears in the rear wheel is the best way for me to head - the front wheel is built on an SON dynamo hub, and I recall the tribulations of putting the bottom bracket into the frame many years ago, and I am not eager to take that out :0)
My initial feeling is that I would like the bike to be 'legal' in the UK, Belgium and France which would limit me to rating of 250W. Oh, and I would like to have a very quiet motor if that can be combined with my other requirements.
I would be very grateful for recommendations from the current crop of motor choices! I would prefer to build the wheel myself, but there may be an unbeatable deal for a ready-built wheel that I should know about?
TORQUE THOUGHTS
I read some references to torque sensors being installed in the bottom bracket but did not read many details of the installation process - presumably this actually means replacing the BB completely?
Do motors exist that have the torque sensor built in? That would be lovely!
Many thanks!
