We have a 74 tooth sprocket for 8mm chain which is our item number SPR-874. This sprocket would need to be machined to fit the go-kart's existing sprocket adapter, or it could be bolted onto a go-kart sprocket so that machining would not be necessary.
Please let us know your thoughts on all of this and we can take it from there.
I have a similar situation with converting my Schwinn trek bike to a cargo bike. Currently, I pedal my bike with an approx. 100# fully loaded cart. So total weight is about 300#. I would like to DIY my bike into an e-bike. I live in New Orleans where the roads are mostly potholes than flat. I am looking at a 500-watt gear reduction motor kit but I cannot find a kit with a gear reduction on your site. Will a scooter kit with low rpm work as well? Can I switch out a motor on a kit for a gear reduction motor? What would be the best motor kit to go about 10-20 mph?
Here is an example of a 36 Volt 600 Watt gear motor kit that we made for a beach wagon, however, it would work equally well on a bicycle and we have a bicycle chain sprocket (item # SPR-B1711) available for the motor in this kit:
These kits are just a few examples and we can make changes to them or start from the ground up with making a kit for your project.
Please let us know if you have any questions.
Thanks for the information.
I'm building a go kart using kartfab plans with parts kit from gopowersports. Which size electric motor kit of yours would I need to power it?
Total expected weight including riders is max 350lbs.
Looking to get approximately 15-20 mph flat ground.
The kit I have came with a 60T 420p drive wheel sprocket and chain and 6" wheels with 14.5" diameter tires. Can I use the sprocket and chain or do I need something else to go with an electric motor?
