1984 Honda Elite CH125

Post by FbGFxVQhO6UHmBZQU » Jun 03 2021 9:54pm

Hi. I'm hoping to change the old scooter to an electric. It is not easy to get a street legal e-scooter in my state so I hope retrofitting will work out. I'll update what is going on as it goes on.

Really appreciate any advice too.

I hope to be able to reach 55mph in a pinch, so I've asked about 72V QS MOTOR.

I just got a quote for a motor and battery and parts. Does it look good?

Code: Select all

1pcsx QS V4 10inch 3000w drum motor wheel
1pcsx 72V150A sabvoton controller
1pcsx bluetooth adapter
1pcsx throttle with switch
1pcsx 12V dc-dc converter
1pcsx CT-22 hall display
1pcsx Alarm
1pcsx 72V10A charger
1pcsx 72V50Ah lithium battery (410x150x153mm)

These are parts preview.

I got another estimate with a different battery size.

Code: Select all

1pcsx 72v QS V4 10inch drum brake motor wheel 100Kph possible speed
1pcsx 72V150A controller
1pcsx bluetooth adapter
1pcsx throttle with switch
1pcsx 12V dc-dc converter
1pcsx display for speed and battery charge
1pcsx Alarm (optional)
1pcsx 72V charger (USA Plug)
1pcsx 72V50Ah lithium battery (220x170x320mm)
I made a template and I think this battery size can work. What do u think?

I'm sure I can grind down the frame some and make a nice box in there for this size battery to slide in and rest an inch or two above the frame into the former gas tank space.

My idea is to bolt this Suzuki swing arm in there just above the parking stand. Is anything wrong with having the swingarm pivot a little lower than the rear axle? It looks like that is what will be the result.

If I understand correctly, then it shouldn't be a problem. You'll see this on most motocross bikes also.

thank you for advice. i think this low rider is really more like the case I will end up with.

the pivot will be lower than wheel axle. but surely not that much lower. it is very encouraging.
