My PV controller and edge 1500w motor are absolutely silent. From hearing my friends ride my bike, I would say my chain/freewheel and knobby tires are louder on the road. Coming from slick tires previously, knobby mountain bike tires actually make a lot of noise on pavement. For absolute silence, get slick tires and a quiet freewheel/cassette.

With a square wave, it's normally a wheeze and vibration transferred to the frame (from the motor).
Absolutely not. It only makes noise during accelerationPowervelocity.com wrote: ↑Jun 08, 2018 4:38 pmWith direct drives, the only two things I can think of as noise sources are the bearings and/or freewheel.
Is the noise present also when you just pushing the wheel with your hand (controller is off)?
Would be interested as well. Also to know how how to compares to a Kelly of sabvoton which seem to be more established products
Ahah wow. 1 month warranty.. even Kelly has 1 year!

Why not provide longer warranties so that people have confidence in buying your products?
I'll buy meanwell anytime Vs other power supplied because of the 5 years warranties. That really show how reliable it is. They wouldn't offer such a long warranty if they have yearly people contacting them about that
