Re: Steep hills that strain the hub motor

When you hear the motor bogging down, pedal harder and release the throttle to the point the motor sounds more normal. Perfect advice, melted the nylon gears on a geared hub motor like yours pushing it to 1000w (48v 20a) when I let it bog down going up a steep hill. It is less likely to happen to y...

Re: DIY vs prebuilt bikes

Welcome to the forum mastermind1234321, DIY setup depends on your mechanical skill. Can you repair a bicycle flat tire? What is your budget? how far do you need to go? Otherwise a factory built ebike will be a reliable workhorse that will probably meet most of your needs and last you years. I am int...

With a voltmeter probe between cell 1 and 2 then between 2 and 3 then 3 and 4 etc. etc and check each voltage reading. You will see which cell is weak a...

Re: $40 electric bike

Correct me if i am wrong but does your dropouts have a space of 150mm? From the picture it looked that way. If it is true you might have lucked out and can replace that geared motor with a powerful 3000w motor. You can run it at 48v and a cheap generic Chinese 9FET controller, if possible trim it do...

Re: Anyone here use a MAC 500/100 watt motor on a Road Bi

Totally agree with d8veh, I have built all three of the ebikes hub motors that you are considering. For a light weight racer the Q100 is the BOMB. The SWXH is a nice motor too. The thing you have to be aware of with the Bafang SWXH is that it is noisier and heavier. The 6T wind I have not worked wit...

Re: Increasing speed with new battery and controller

I've seen a Prodeco Outlaw in person that was chained outside a store and gave it a look over. If you're going to feed the motor more power (especially amps) in an attempt to reach 40mph, the phase wires will need to be upgraded (it has the dinky 6 pin "XLR" type connectors) and the torqu...

It is a matter of personal endurance. I agree with the MadRhino, though it is not that hard to ride in winter conditions with the right gear. Spike tires are the first priority. Poagies are also very helpful in keeping your hands warm because that is the part that gets the coldest when riding in wi...

Re: EUropean Group Buy for MXUS 3000W Hub Motor ~187€ + Ship

I am very interested in this. I believe that the MXUS 3000w hubmotor has potential. What has me on the fence is the skinny phase wires. I have a 1000w MXUS now and has the same size wire. The wires already get very hot when i run an infineon at 2000w. Can you imagine the new motor at 3-4000w? This h...

I think this may be when you first press the throttle, it is the minimum throttle level that is applied. if setting it to 1% it shuould give a good range of throttle, whereas 100% turns the throttle into an on/off switch.

Re: HELP!! Tried to connect battery and it sparks

Yes but we are talking about a 50 cent item. Thanks for the capacitors information, did not know that. For me the big trouble I had was the wearing of the contacts due to constant spark upon connection, though i agree it is only a 50 cent item. That 50 cent item can cost you when you least expect.
