Re: Standard formula for Calculating Ebike Range

With respect to lower wattage limits and slower top speeds for other Countries (i.e. 250W limit, and 25 KPH Top Speeds in many countries) it might make sense to add the following range calculation, which due to the slower top speed, would naturally be MORE efficient, and correlate to longer range fo...

Standard formula for Calculating Ebike Range

There is absolutely NOTHING more confusing to the inexperienced ebike purchaser that understanding potential range with respect to the ebikes they are considering. So many ebike manufacturers and retailers embellish range claims using tricks that we experienced ebikers know are deceptive at best and...

And "It's too small".

(It's a 22"Frame, the largest they make in this model)
So apparently this dude is like 6' 20". :roll:

Built this one for a customer.
Box had a hole and a scratch on the rim, so he sent it back.

Re: KIT: 45mm DD Hub / 19" Moto / 18F Sine Wave / CA3 $799.95

My own branding...no MXUS logo. that's a downgrade that dimishes resale value. you'll need to sandblast that off or lower the price by what it costs to have it done professionally. It actually makes it very easy for me to identify motors that I have sold, so I can provide support and warranty for t...

Re: Killed hub motor on 1st run, lots of friction now.

If controller is a KT model (Based on your comment regarding the display being a KT-LCD3), then I would recommend replacing the controller. Another KT controller would be easy to swap out, but they are pretty modest controllers, honestly. The 12FET ones, with pseudo sine wave are decent, though. Get...

Re: "Edge" DD hubmotor, 1500W, 35mm, Al core

The 4T winding is about 11 RPM per volt, so at 72V Nominal, you are pushing upwards of 800 RPM. In a 20" Wheel, that would be close to 50 MPH top speed.
Great Motor in a small wheel, paired with a great controller and the respectable Samsung 30Q cells. It's a hard combo to beat.

Thanks for the shipping quote..i think ill pick one up soon. At the moment i have an 18fet sinewave 72v 2000w controller it sometimes runs perfect with the motor. But at random times..the motor sputters. It comes and goes. Sometimes the sputtering will smooth out and stop as i go faster but other t...

Re: Seal hub with silicone?

Hey Guys, Is it smart to seal the hub's side covers with silicone? I've seen it done but I learned that if something is 99% sealed it's worst than 90% sealed since the moisture that may get sucked into the hub when it's hot will have a harder time getting out (if ever). Don't seal. Drill a few Weep...

I'm going to put my pride on the shelf and admit that you have a very valid point, EG.

I do think I have a great pro...

Re: Sine Wave Controllers 6FET/12FET/18FET

These are a simulated sine wave but very well done. DD hub motors run virtually silent and the power density is really impressive for their size. About the only controllers more power dense are the Adaptto, or the phase runner, considering it's miniscule size.
