Will not a 30 Amp (current limited) controller drawing on a battery with a limit 15 Amps simply shut the battery down?Nobuo wrote:With a 1000W motor and regen I find two awesome things, the first is that I use my break pads a 5% as much. the 95% of break is done by the motor.
the second is that I measured with an amp meter that it really charge useful energy to the battery, 5% to 10% of the entire capacity.
the small mxus is for a super stealthy and lightweight build. An aluminium front suspension with a front hub (XF07) moved by a 12 fet 600W controller (greentime).
It will be with a seat bag small battery 48V 11,6Ah lithium-ion battery. it will be BMS limited to 15A
So the aim is to be very light, almost invisible and reliable to use without the motor, in full pedal mode.
I couldn't choose winding options, lately I hit myself always with vendors that don't understand what winding / kv is..
The motor is very cheap, it can be bought with no shipping cost and with a shipping method that doesn't include taxes in EU, so the price I paid is the total cost.
It cost $100 each one if you buy two units

The pack I'm gonna build it myself (of course ) it will be with panasonic PF. 2.5Kg. cost $220

Go get a leafmotor, mxus v2 or some other larger motor that can actually handle what you're pumping into it. It'll not only perform better per watt inputted.. your range will also improve dramatically.
Shove 4000w into a 16lb. leafmotor like i am.. you'll love it.
That is incredible and cool you tested it so hard now we know !motomech wrote:It's a MXUS geared, 2.3 Kg.fellow wrote:What is the geared "ebike kit 350W motor" exactly? Q100H, Bafang (8fun) or something else? 2500W cont, was it without oil cooling?
As solid as the the MXUS mini is, you need to be a little careful here, there is a limit to what it will take.I just ordered a 26 inch front wheel with the 250/350 MXUS XF07 Hub motor , will be powered with a 48v -64v 20A continuous 30A max controller with a 48v 12AH 30A li-ion battery pack
I love my RM too , had since '99 it just seems perfect for me I have no desire to replace it with a 27 or 29er none at all. I have just switched my plans and will build a road ebike and keep the RM for trail riding.motomech wrote:My first Ebike was a frt. mounted MXUS geared mini in my '03 Rocky Mountain edge w/ a rack battery;
The rack battery didn't last very long so I went w/ LiPoly in a frame bag;
The MXUS motor was great! I rode it a number of years and 1,000's of miles. Eventually the axle bearings started to make noise and rather than fix it, I gave it to a kid in the neighborhood(Last I heard, he was still using it).
My Rocky Mountain is an XL frame, great for battery space, but the top tube was a little too high to be comfortable, so I changed to 24" wheels and 2WD. The 2WD was too very small Q100's. I had an larger geared Ezee V1, so I put that on the rear and that's the bike I ride today;
The Rocky Mountain has been solid as a rock. 6 Years and all I have really done is tune and put seals in the Fox air shock. All the linkages, seals and bearings are still original. As is the frt. Bomber fork! The paint still looks new. I luv my Rocky Mountain!
Its a guess on my part but think it might workAlan B wrote: ↑May 14, 2015 11:22 pmI haven't tried this but I suspect that you'll get significantly more resistance with a locked clutch gearmotor than with a DD hub. You have the losses of the reversed gear train and a motor spinning about 6 times as fast. So instead of a continuously small resistance you will have a continuously not so small resistance. They put clutches in them for a reason.
