I wanted to convert a gas powered mini bike to electric for my daughter (and me too lol) Need enough power to haul my 200 lbs around. We will be mostly be using it on grass and wooded trails with a few slight inclines but not too steep. Speed is not too important to me but having enough tourque for me to keep it moving for a 5-6 mile range. I already have 4 -12 volt 12ah batteries which I have room to mount in the bike.
Here is what I think I will want in a kit.
#MOT-481000B (48V 1000W motor/with the base plate)
#SPD-481000C (48V 1000W controller)
#THR-50 (48V full twist throttle/with power meter)
#LEV-30 (left hand brake lever/switch)
#CHR-48V1.6A3P (battery charger/3port)
#CNX-515 (charger port with wires)
#SWT-125 (power switch with wires)
#FUS-364 (ato fuse holder with 14 gauge wires)
#FUS-ATO40 (10 pack of 40amp blade fuses) --I think 40amp fuses is what I need
Also I would like all the matching connectors with labels and battery connectors to make it easier for me to plug and play lol
What do you think about all this? Do you think this would be sufficient for my needs? If so, would you make this up into a kit for me to order. I live in Canada so I hope there is not problem shipping this stuff to me.
On another note, I know the motor comes with a 8mm chain sprocket. I think the bike has a rear spocket for a #35 chain. They are very close in size, but will it work or would the chain tend to pop off or wear on the sprocket and chain unusually?
I don't know if I can find a rear sprocket for 8mm chain that would fit my bike. I could order the #SPR-3510 ( #35 sprocket). Any input on this would be appreciated.
We ship parts to Canada almost everyday so that is no problem for us at all.
8mm and #35 sprockets and chains are not interchangeable with each other. The pins on 8mm chain are around 1/8 inch closer together than the pins are on #35 chain which is too much of a difference for them to be used with each other.
Our SPR-3510 10 tooth sprocket for #35 chain is a direct fit for the MOT-48100B motor.
I can go ahead and make the kit if you are ready. Would you like the SPR-3510 to be included with the kit?
Well I finally got around to converting that mini bike to electric with 48v 1000 watt motor/
Everything went pretty smooth after figuring out where I wanted to mount everything. Took some looking to find the right size waterproof electrical box to mount the controller in. I was able to mount the on/off switch and the charging port in the box too. Had to bore the sprocket out a bit to accept the right chain size sprocket but no big deal. The kit you guys made me was super easy to install everything. Already had the plugs on the end of all wires and labelled. The bike turned out great. Lots of torque and enough speed. I will have to wait till it gets warmer out to figure out the exact speed and range I get with this setup.
I was teaching my young daughter how to ride it on the weekend. She was having a hard time getting use to it. Its a lot of torque right off the start for her. I tried telling her not to panic when she gets moving and not to jerk the throttle back like you see people do on Americas funniest home videos. And what does she do.....she panics and goes full throttle into the side of my boat in the driveway. LOL She wasn't hurt but broke the front fender right off. We were both laughing our butts off afterwards. I think we will go out in the wide open field next time.
Thanks again for your help and your kit you made up for me. Everything worked perfect.
I attached a few pics of the mod.
I want to do this to my son's Doodle minibike. What kind of operating time are you getting out of this set up on average?
For anyone else reading this who needs a sprocket for #35 chain or #420 chain for their motor we have a sprocket for #35 chain that fits our MOT-481000B motor along with all other MY1020 and ZY1020 motors including Boma 48 Volt 1500, 1600 and 1800 Watt brushless motors and 60 Volt 2000 Watt brushless motors.
This is our item # SPR-3510 and it is available on our #35 Chain Sprockets page.
We also have a sprocket for #40, #41 and #420 chain with 11 teeth that fit the same motors as listed above.
It is our item # SPR-42011 and it is available on our #40, #41 and #420 Chain Sprockets page.
