Re: Building a Powerful Ebike

I am planing to build a powerful ebike [my 2nd one] but I not sure what I need. First I'm either gonna need a fat bike or a regular bike with 150mm dropout for obvious reasons but I'm not sure what to get as I dont want any of those frames that look like dirt bikes like the grey borg or stealth bom...

Re: A2B Metro Rearming 3kW Motor + 20700B x 104

Those spoke angles are steep I can see you had to fight those nipples, 65 degree spoke angle is ideal so a 2 cross is most I'd go on that size wheel but it's built so give it a whirl see how it rolls. I got myself a kuberg freerider pro second hand thats had new bearings and a rebuild and I'm build...

Re: A2B Metro Rearming 3kW Motor + 20700B x 104

Had these 9G 165mm laying around.

16 inch chinese moto rim x qs 205 50H x Triple cross pattern worked, look just ok.

Have ordered 94mm long ones for 1 cross lacing before attempting triple one.

Will try the wheel tomorrow and keep an eye

Re: A2B Metro Rearming 3kW Motor + 20700B x 104

The fork is not too hard to take apart. The caps with the preload adjusters are the hardest part due to limited clearance. After spending a bunch of time to make a thin wall socket, I found they weren't too tight and was able to remove them with a large needlenose pliers. Fork Sliders Off.jpg Fork ...

Re: A2B Metro Rearming 3kW Motor + 20700B x 104

It is getting difficult to handle the bike as fork suddenly got stiff and it feels like no damping happens at all.
Will be looking to repair or replace the forks with DNM usd-8. This implies cutting the head tube down and also some clever clean metal work...

Was KLS6035s. Got it cleaned from some green stuff.

Re: A2B Metro Rearming 3kW Motor + 20700B x 104

Controller died about week ago as a result of Water ingress. I can clearly see charcoal stains under the last mosfet and smell burnt silicone

I had to install KBL48501E and it accelerates and rides well. :D

Alternative fork for A2B Metro

Hi,
I am looking to find dual crown fork to fit A2B metro.
I am not very happy with handling, especially while accelerating.
Would be great to hear if anyone has suggestions.
cheers.

Re: A2B Metro Rearming 3kW Motor + 20700B x 104

Looks great. Maybe reduce the current limit on the controller slightly so it doesn't cut out. With my stock motor, external controller at 52v, the most the motor can draw is less than 60A. With 100A peak, that thing should be moving pretty good. I managed to change the ride to more reasonable speed...

Re: A2B Metro Rearming 3kW Motor + 20700B x 104

All works great so far. Controller got little warm while hub was few degrees above the ambient temp. If you are not carefully, the controller cuts out for sec near the 100A battery current mark, but overall acceleration well above needed in the city. https://uploads.tapatalk-cdn.com/20170918/710d2da...

Re: A2B Metro Rearming 3kW Motor + 20700B x 104

looking nice! the more plates stacked together the better. i did a similar design with 3mm layers, i think i had 20+ mm on each side grabbing the axle. make sure there is NO play in the slot if it doesnt bolt shut, as if there is itle chew away with regen/acceleration until it slops back and forth....

Re: A2B Metro Rearming 3kW Motor + 20700B x 104

Yup you are better off getting someone to help you attach that added steel to the frame. If that was mine, I'd do a horizontal slotted Torque Arm so you can slide your motor in, then some sort of allen key to fully enclose the axle. This would also be the perfect opportunity to change the wheel bas...

Spoke to a couple of workshops in London who can technically weld the thing with no problem but they hesitate to touch the bike part... they are worried abou potential legal issues if any failure/accident occurs to bike.
