I would appreciate some advice about the best type of hub motor for my project. I’m converting a full suspension Kick Bike to use as a “sporty” mobility device.
(I’m posting this here because the kick-bike is basically a bicycle frame with 20” wheels and the standing scooter section seems to deal more with scooters with small wheels.)
I’m going to attach a seat and will alternate standing/sitting.
Needs:
- The rear spacing is only 100 mm so I’ll need to use a front motor in back. (20” wheels)
- no need to go above 20 mph.
- need to be able to climb short, but potentially steep hills as I ride around local parks, and on bike trails.
- ideally, would like to use the 12s Lipo packs I have on hand (around 50v fully charged).
- need a reliable system as I am limited in my ability to walk back to the car in the case of a breakdown.
- I’m 170 lbs and total riding weight of myself and scooter will be 240-250 lbs depending on motor choice.
My first thought was the ideal motor might be something like a 10T MAC or BMC but neither appear to be available anywhere.
Questions:
1. Geared or DD?
2. If geared (and considering no MAC/BMC available), any suggestions?
3. If DD, any suggestions for a lower speed, higher torque motor that could occasionally handle lots of phase amps(?) to get 250 lbs (total) up short hills at slower speeds?
I realize I could just grab a cheap option like something off Amazon/Ebay, or an Ebikeling 500w geared (which, sounds like is probably a true 350w) and just make do. However, given my need for reliability and ability to get me up short hills (without having to race up it at max speeds), I’m wondering if something cheap will leave me needing more power (or in the worst case, stranded).
This will mostly be for gentle cruising around and getting myself out in the sun each day. That said, when I need to power up a short, (but steep )hill at 10 mph I’d like to avoid burning up my system.
Very grateful for any thoughts.
