Hey gang, this is my first EV build so bear with me if I ask something stupid... I have done quite a bit of reading and research so hopefully, it's not too bad.
I've got what I believe (the VIN plate is quite faded) is a 1970 Motobecane 50V moped... well, really it's the Canadian N50 but as I understand they're basically the same. I bought it off a guy who wasn't the original owner. He had a plan to rebuild it a long time ago and instead it sat in storage. I found a lot of old vines around the drivetrain so I think he's using the term "storage" pretty loosely.
I'm building this as a city commuter for my wife and would be great to have a range of about 40kms. I'd like it to be able to cruise at 30-40kph with the ability to push it for short bursts up to 60kph or so if needed. It's mostly flat terrain with lots of stop and go at traffic lights. It will have functional pedals so it appears legal but they won't really be used. The estimated total weight including: wife, moped, battery and motor is about 220lbs.
Does this setup seem like it would be a good fit for what I'm looking to achieve?
QS 72v 3000w hub motor (205)
Sabvoton Controller 72200
72v 20ah Li-ion battery with 45A BMS
I'd like to get the EV components ordered ASAP, since I'm sure shipping will take a long time. Is there anything else I need to consider before I pull the trigger on getting them?
The one problem I'll have to solve is that the moped swingarm dropout is 125mm and the QS motor is 150mm. Are there thinner hub motors out there? I couldn't find much in the 3kw range if there is. Otherwise, I'm looking at stretching the swingarm I've got to fit. Plus I'd need to make sure there's room for a disc brake. Is that too far of a stretch do you think?
