Definitely looking into Grin. Not sure if their motor is too much for me. I should mention I'm looking more for a pedal assist vs a throttle motor. That might noarrow the search further.Grin has quality stuff, but it isn't cheap. A bike with pinion gears and powerful rear hub motor would be a hoot to ride.
Many e-bikes use torque sensing which does precisely what you describe e-bikes not doing. So I either do not understand what you are talking about or you are misinformed....
Pedal assist is very crude. Remember, the sensor has no way to know how hard you're pedaling, it only gives a predetermined amount of juice to the motor, whereas w/ a throttle you can add exactly how little or how much juice to the wheel because your legs are continually feeding real time power data to your brain. Always use your brain instead of the electronics because there are more possible synaptic connections in your head than there are atoms in the known universe (Dr Richard Restak's book "The Brain Has a Mind of it's Own"). AI will never be able to compete w/ that.
Yup. 4 or so years ago. Vintage 23 year old 21 speed Giant "Nutra" transformed into an ebike by virtue of a 250w front hub and a simple throttle. I can ride it like a Class 0, or touch the throttle to get some sweet Class 2 assist.There's not much about people who have done this, just the speculation it or the concern with pricing. I already have a touring bike with. a Pinion P1.18 and I want to add a rear-hub motor with a battery.
What are my options? Has anyone done something similar?
