Do electric hub motors need breaking in?

[steve marino]

Just replaced the geared hub motor on my bike w/ a new one (low end Ancheer e-bike, 36V, 250W), and it is only getting me to 14mph w/o pedaling. My old motor would go 17-18MPH w/ no assist. In my old slot car racing days, I remember that after those electric motors had some miles on them they got faster. Is it the same w/ a bike hub motor?

Your old slot car motors used brushed dc motors and the breakin was for the brushess

You ancheer motor is brushless and needs no breakin

That's pretty funny Mike. Thanks for educating me on the differences between brushed and brushless motors linklemming. I guess I just have a granny motor then. What I forgot to mention was that it was my older bike (exact same model but bought 1 1/2 years ago) that would go 18MPH. Maybe Ancheer downgraded the controller or motor or something on the newer bikes. Since it's an expensive proposition to get more speed on this bike, I will be content w/ what I have and take solace in knowing that I will be in better shape for having to pedal a little more. I read somewhere to look for a jumper wire on the controller's wiring harness that might be there to keep things down to EU regs, so will give that a peek.

Ancheer could have changed the windings on the motor to lower the top speed and give it more torque for heavier loads.

The new bike feels like it has less torque AND less speed than my old one. Maybe I just got a good one on the first go around. For 3-4MPH difference I won't sweat it. With only a 250W motor and a 36V 8AH battery this one is entry level all the way. Might sell it later on and buy a 500W front hub motor kit for my other bike. Not that excited about a front mounted hub motor, but that's the quick and easy way to go.

One thing I remember from my motorcycle days (and I have the scars to show for it), the faster the bike will go the faster I will ride it, which is not always a good thing. 50 years ago I had a Honda 160 Dream and my best friend had exactly the same bike, and his would outrun mine in a 1/4 mile run and for top speed too, so there's always some variance in these things.

All new motors MUST be ridden everyday the sun comes up, for a month.

@Thomas Jaszewski , a great practice for all ebikes, I think!!!

Well unless you had a special built Honda it was a 150 Dream . They made the 150 Dream and 305 Dream and a CB-160 Scrambler . I had every one of them . Cant help you with the Ancheer tho .
