Re: Is this a deal or what ......

Sorry if I brought this thread back to life, but for anyone interested in trying one of the "HPC" bikes on aliexpress- DON'T DO IT! You will be throwing away your money... If you look at the vendors selling the HPC bikes, they are never a corporation, never have a website, and have no feedback. Most...

Re: Prodeco Phantom X 6 months of ownership

Good bike! Best I have seen for the price of ~$1100. Have heard nothing but good things from dealers about Prodecco as well. American made, reliable, decent quality, not much more you can ask for in a bike at this price point! I recommend them routinely when asked a good bike for around $1000... I h...

Re: Hi-Powered Cycles

Hello Neptronix. 1)Good point about the 18mph cruise speed. It is now listed under the FAQ section. http://hi-powercycles.com/contactus.sc 2)We have found that our customers average anywhere from 13-22 Amps over the course of a ride. So we find a 10Ah rating at ~1.5C of our Lifepo4 batteries to be v...

Re: BMC v4 motor?

What would you like us to be straight with you about? Ask away. We have tested these motors extensively from the beginning. As neptronix stated, "8g is overkill," and he might be correct. However, the reason we did this is because with the standard 11g wire to the axle, we have been burnt from just ...

Re: BMC V4 motor

Oh yeah, and another thing, I have killed the BMC V4C and BMC V4T on 50A, so don't expect to be pumping 50A continuous up the steepest grades. Most people will not torture the motors as hard as I do, but still 50A on heavy hills for prolonged periods is not recommended for the BMC V4 motors...

Re: BMC v4 motor?

We tested the V4 a couple months back. Besides cogging on start up, the motor was quite powerful at its mid range. Top speed we tested was 40mph with a 50amp controller and 51.2v battery. Efficiency at speed was slightly higher than the v3 (black lightning) Too bad we burnt it up so soon or we would...

It's reliable, stays cool, and outputs a steady 50A when accelerating or hill climbing. Top speed is 40 MPH +/- 1 MPH at 48V (good battery with minimal...

Hello, Heat build up is no problem for up to 3000W or so- more if you use 10g wires at the shaft. If you plan on loading 9000W like a certain member on this forum is using, I would definately go for the much larger crystalyte!!!

Bring on the Crystalyte 5303! I know first hand it will not break 40 MPH!!! Amps at 38 MPH leveled off to about 36A. Controller was putting out a maximum of 46A under acceleration. Correct me if I'm wrong, but the 5303 will go 37-38 MPH on 48V. The production version of this motor should be between ...
