You could have described me Brew. I too have a M20i, and purchased it for the very same reasons. Only here in the UK it's limited to 16mph accordingly I average 120 miles per charge.Hi All. I've had my M20i for a couple months now and am really enjoying it. I think this bike is more for an older rider like me who have lost some pedal power over the years. It really makes riding fun again and I feel almost as fast as I was 20-30 years ago. Back then may I would average 20-22 mph for a 30-40 mile ride, now I’m lucky to be 16-17 mph on a regular bike and that’s at the end of the season.
With my Gain I can now average 20 mph while keeping my heart rate in line to where it should be at my age. Head wind, no problem, hills, no problem.
I’m fine with the 20 mph limit and feel that if it was any higher the battery life would not be as good.
In the highest setting I can go 18 miles before it goes to 50% battery, in medium setting it will go to 20 to 22 miles and at the lowest setting it will go 28 – 30 miles before 50%. Keep in mind it depends a lot on headwinds and hills of the route I may be on.
Only a couple small issues I have are some creaking in the stem/handle bar area.
Misaligned rear disc causing it to rub and I’m having a hard time adjusting it. It appears that the bottom mounting surface that the caliper bolts rest on have a slight curve causing the bolt head to slip out of alignment.
The other issue for me is the rear gearing. I like to spin more than a slow grind and the shift point at the motor turn off point the gear spacing seems to be too large for me. If I shift I’m doing the slow grind to stay above 20, if I shift I’m spinning a bit too fast to stay above 20. I suppose I can try a different cassette in back to solve this.
Anyway I would recommend this bike to anyone who’ve lost a few strokes and want to feel fast again.
BTW we purchased a TREK CrossRip + so she can finally ride with me and that has an assist speed up to 27 mph I believe. She really thinks it’s funny when she can blow by me on the hills but she has to put it in the turbo mode in order to because that is one heavy bike at 46 lbs.
