This thread (Lars in particular) has helped me a great deal to decide which solution to go for.
So after countless hours doing research I went for this motor as well. The last piece of the puzzle (battery) finally arrived
today so I had the chance to test it out. Here is my little review.
This Is my first conversion to an e-bike so I don't have much to compare with but in my opinion the motor is plenty powerful.
At least in the top 2 speed selections. For instance, when in turbo, I can easily ride on the rear wheel for quite some time
And taking a u-turn feels almost unsafe. Hills are no obstacle. I can easily maintain a fast pace even though it's quite steep.
One has to keep on pedaling continuously though, just like without a motor. Which imho is a plus. The motor shuts off immediately
after no pedal input so it's obviously quite power efficient.
The design is great and well thought through and from one side it's almost hidden behind the gear. I was after a "stealthy" look
and added some color to the outer ring to match the bike better. My battery is compact (36V/8Ah) and is in a small bag under
the seat. The system has a minimum amount of wire clutter so the bike still looks almost non-electric. Total weight 19KG which
I'm perfectly fine with on a mountain bike with a front damper.
Prior to ordering I was unsure whether it would fit my bike properly since the crank opening is 73mm while the instruction
clearly states max 68mm. Well, it fits perfectly but the included fastening screws and bushes are too short so that had to
be addressed. I also had to sand the opening to get the motor to fit inside. The rest was real simple. All brackets and bolts
fit just fine.
I felt no weird vibrations or other misbehaviour during the 5km test ride. I guess fastening the motor with all intended brackets
is a must considering the force it operates with. The noise it makes reminds me of the power windows in my car. Totally acceptable.
The only thing I am uncertain about is whether my chain is now a bit too short?
Well anyway, hope this was of any help.
Og igjen takk for god info Lars
