I'm looking for a motor battery set up to build a budget e-bike, but I don't want to cheap out too much and wind up with a bike I can't use.
I'm hoping to use the bike for quick trips into town (3km), and for commuting to some of my closer work locations (20 to 30 km). At that distance, I need a speed of ~30 km /hr, otherwise, I'd probably drive the car. I often have to drive further than that, so the bike won't be able to replace the car, even in the summer. I can plug in at work, so range for a one way trip is acceptable. It's relatively flat in this area, but there's no predicting headwinds. Of course I'm ready and willing to pedal assist, but I don't want to be sweaty and tired at the start of a shift.
A kit with lifepo4 batteries is out of my price range for now. It looks like I can get 24 aH sla batteries for around $60. Is 24 aH at 36 V a realistic capacity for this speed and range?
The currie motors seem to be much cheaper than anything else out there. I realize thats because they are brushed motors, but is the drop in efficiency noticable? The link here is what I had in mind. 36 Volt 500 Watt Motor, Controller, Throttle | Monster Scooter Parts I know currie has a bicycle kit that would be much easier to install, but I don't think the 24 V 450 watt kit would have enough oomph. A 500 W motor is the legal limit in Ontario, but I don't think anyone's going to check my bike to see if its motor is >500 or not.
