Hi. I sold my HS-142F and will sell my motorcycle as soon as possible. I have a 36V 500W ebike and really like the torque and how quiet it is. The top speed is around 22-23 mph before the limiter kicks in and stops the motor. I found a good deal on batteries and will buy in small bulk enough to run the bike at 18-20 mph for 50 miles on one charge. However, 20 mph is pretty damn slow. So... I want to make a powerful ebike hybrid. Initially, I wanted to do a HS-142F reverse gearbox to test this for everyone but after thinking I don't want to deal with a big motor sounds.
So, as of now I am thinking a 48V 1500W fat tire ebike that will have a top speed of about 45 mph for me (light, light rider and in a tuck) and enough batteries for 50 mile range at 30 mph. But, I hate the ideal of just running out of juice so I was thinking about adding a generator. But not the big 1000W DC-AC generators out there but rather a small 25cc motor (should be quiet) into a 200W brushed motor to charge the batteries incase I am running low on juice on a ride. Can this be done? The 25cc motor will turn the brushed 200W motor and that will create a current and with a boost controller I can use that to charge my batteries? Any thoughts. Take a look at my picture below for what I am thinking. This is all preliminary and atm I am just building the 36V ebike battery bank but can transfer that to the new bike.
Also, I like a fat tire bike because I tried to do an aggressive lean on my 2" mountain bike tires and low side causing a sprained wrist for 2 months...
