I choose to ride leg powered whenever I can and power up for hills and inclines that would hurt my knee, and in nasty ocean headwinds. I've had zero problem climbing 25 degree grades with my drive at a pretty good speed. You can read up on what I have if you want (or not):

If you have any other questions I'd be happy to try to answer. For reference, I previously owned a dedicated electric bike with a hub front motor, had it about a year, maybe a little more, when I first returned to riding after a 20 year absence.
That is a great write-up. I appreciate it. I love hearing of experiences with a light weight build. You have a great setup there!
good to hear they have minimized that RC motor whine. The PAS sounds great. Probably the best Friction Drive example I have seen. Looks like a viable option to a small hub drive, one that works very well for your usage. Good to see bikes that are pedaled like a bike with e-assist (as opposed to converting a bike to an electric mini-bike).
I did a little research on the motor you listed. I agree, for your application, a small 200-350 watt motor can be useful for short ranges on a light bike. I always enjoy seeing light weight builds. Its my passion.
Your build looks like a 250 watt motor that saves 0.5 to 1.1 kg over a small hub motor. It works well on your setup.
I get frustrated with a company like OneMotor specs are a little opaque, and seem to me to be misleading. Maybe I missed something.

For instance, the <5lb package has a 130Whr battery, typically 10s1P. That is capable of continuously giving about 4 amps, which puts us at 130 watts continuous. Maybe it can do 8 amps if they are using the best chemistry available. Not exactly a 750 watt motor. It says the top speed is 20mph, which is about 150+ watts on an efficient drop bar bike or 340W on a typical mountain bike. That could be brutal on that little battery – and more practical on their larger battery.
The motor with the small battery would typically be labeled as a 250 watt set up (or whatever the continuous power is), not 750 peak power with a larger battery. With a larger battery, I would guess it as a 350 watt motor as you are not really going to want to pull more than 10 amps continuous on that battery.
