I also suggest lithium ion batteries rather than those heavy lead acid batteries...it may cost a little more...but there much lighter and more effcient
Ok. First of all you should get a power control module and a throttle and consider a fuse somewhere on your positive wire. I hope you know how to hook up your batteries. You can hook them up in series or parallel. Look it up. Read about it.You should only have two of those batteries on there.Also if you charge those batteries on the concrete even once they are ruined. That motor is very weak. 750 Watts is 1 horsepower. Consider the weight of the batteries and your bike too. Good luck kid
if you look around you can get a motor control and motor 300 watt . out of those electric gulf cart caddies. thats what im doing with mine . its got a distance control with auto shut off or a disable feature for that . so the caddy didnt run away from u. great for testing .it its got a 12 volt 45 amp high torq pmm motor . looks like a starter size round but see the control it hooks up to 12 volt car battery .
Glad you got it sorted out. 1000 watts sounds like rocket shop stuff. I think mine's about 250 watts using the motor from an old battery lawn mower. I'm just finnishing the pulse width modulation system. I've just made an electric outboard motor and a compound archery bow but the e-bike seems just as envolved and as much fun.
@Rayxl1 nice. i think you need like 3500 watts to do about 40 mph. so with mine it should do about 25 ok. i checked out your outboard motor it looks really cool! what kind of batteries r u using? for an ebike i think sealed lead acid is best. a lot will argue that lithium is the way to go, yah if you wanna spend like $300 for less amp hour batteries. let me know when you get this project all set up i'd like to see it! what r u using to regulate speed? also make sure you set up the gear ratio
@snowboardr147852 I just use an ordiary car battery for the outboard motor and it works fine even in this deep cycle application. For the e-bike I've got an old bike I can make all the mistakes on before I convert a good bike. I've made a pulse width modulating speed controller which runs at 330hz. This drives a pack of fet transistors rated at 120 amps. I'll make a video when I get something running, hopefully soon.
@Rayxl1 to a max speed you think the motor will do. otherwise it won't work so well. for example, when i first attempted this project i used a 26 in wheel. that was terrible because the motor was trying to do like 55 mph haha.
The motor looks big enough to drive the bike at a reasonable speed but at a rough guess I would think it needs to spin at about 3000 rpm to be running at its most efficient, in other words giving close to ets maximum power without consuming too much battery energy. It might be quite difficault to do but at another rough guess I would try a 50 to one reduction on the gearing and see how it goes. At least you've got further than me. I've only just started on my e-bike project!
@Rayxl1 haha i've come a long way from this video. i now have nice 18 ah brand new batteries. also a 1000 watt motor. i'm currently changing the gear ratio so it'll go about 28 mph. i used to have a ratio so it would go like 33 mph but it would only do that on big down hills. i have been really busy lately but i how to put up new vids soon. and that's cool your starting an e-bike project! they are so fun! if you need any help let me no. i no formulas and stuff for gear ratio.
@elobiretv haha this is my old setup. kind of a test bike. they were really old batteries. the probably on got like 2 ah each. i have new ones now that are 18 ah each and only weigh 20 lbs each, compared to the old 35 lbs ones i used to have.
@luftschutz the plate came from an electric scooter. just look on amazon or something. search for ezip.
and i now have a completely new setup. have a 1000w controller, 1000w motor, and 3 new batteries. lol the big ones where so big and old. i have new batteries now each weigh 20 lbs. and 18 ah each. i get an average speed of 16 mph. tops out at like 24 mph. i get around 12 miles on one charge.
@RdElias haha exactly what i did. i now have 3 sla batteries. 20 lbs each. 18 ah each. and 1000w motor and 1000w controller. it runs great. i needed to put a smaller wheel on it though for more torque and less speed. lol i now have a 12 inch wheel on the back and cannot use the pedals.
Definately a 1000W motor would work and give you lots of power. If you have three batteries then you should get a 36 Volt motor. This will use less amps and the batteries will last longer verses if you ran it at 24V. I have built a bicycle pusher trailer with two motors for a total of 600W, (running on 24V) and there seems to be decent power. You can check out my channel and see it in action.
godamn!!!! bro sorry to sayit but no!!!!! thats def. a fail..... way to many batterys way to ugly def. not strong .... stop it

that will be way to heavy to move anywhere. why do you need 3 massive batts?

Hi this is Bill.Where did you get the bracket that mounts the motor to the bike.All you should need is a 500 0r 600 watt motor.

Hi From California USA
I like your video I think you are doing greate.. I think you need to put a bigger motor and smaller batteries ,,,,
