A valid point. I admit I really like the concept of a mid drive. I am afraid I was letting that influence my good judgement (questionable under the best of circumstances). This thing has a really skinny fork. It is so close that I will have to have the motor to actually see if it fits. Note: The Q75, Q85 and Q100 all have the same indifference point in common.

I want the extra acceleration of a lower gear particularly when crossing 6-10 lane roadways. That is not the time to discover your motor assist is not working (dead battery, faulty wiring, whatever) and all you have is a road gear.mfj197 said:... Singlespeed makes quite a lot of sense with a hub motor.
The argument can be and has been made that rim brakes are as effective as disk brakes. Here is one interesting piece on the subject: http://www.rodbikes.com/articles/disco-fever/disco-fever.htmlmfj197 said:... using just sidepull caliper brakes ...
You missed the point about it being sensorless. The 250 watt number is often referenced as the equivalent of the average adult male pedaling a bicycle. That seems like a good starting point.mfj197 said:But why is more power needed? "Only" 200 watts is actually a goodly amount of power for a cyclist.

Fortunately PAS can be disabled or ignored. I prefer to have a throttle.Alex W said:I'd recommend riding a PAS bike (which is what the BBS0* builds up into) ...
Another thing I am considering is that with a properly packaged front hub drive (controller and battery in a small handlebar bag along with an attached thumb throttle) one could quickly convert back to a sub 20 pound pedal only road bike (of course that would require another front wheel build). A bit like having your cake and eating it too.
Question:
Does anyone have any experience with the Bafang SWXU that they would care to share?
