Hello motorizedbicycling community! I have been using this forum for a few months now for help with my bike and so I figured I'd make an account and be apart of it. I will try and post a picture of it tomorrow since after all this work I'm pretty proud of it. Now on to my question: My chain...

So, I recently bought this kit: https://www.gasbike.net/collections/bicycle-engine-kits/products/79cc-monster-90-bike-engine-kit-complete-4-stroke-kit I threw it on a brand new beach cruiser and it was riding fine for a day or two. Then the chain tensioner came loose and broke my spokes. (I'm...

hey guys, so my first build i ran it and the engine idled flawlessly. For a while, then the bike would no longer idle. When I pull the clutch the RPMS shoot sky high. When I leave the clutch it’s always trying to go like a car placed in “drive”. Any ideas? Thanks guys!

HEY GUYS! Just built my first beauty. It’s running well and strong aside from when I picked up a nail. However I have a question about how you guys like to secure your gas tank and mufflers. My attached components are tending to vibrate loose. Am I just going too fast? Or if there another way to...

So this is my first build, and once it was all together, I found that on disengaging the clutch the bike would not roll but what little slack the chain would allow before the chain would run out of play and snag. I’ve gone through clutch re-set and cleaning procedures, such as cleaning the pad...

Hello guys! First - Thank you for taking the time to read my post. I need some help finding an engine to buy. So I have a small (seven months) experience with an chinese engine I brought off e-bay. Actually i knew that the engine probably wont be the best quality, but i just wanted to first try...

Hi, I’m originally from Chicago but my wife and I now live in SoCal. We both have Electra Townie Balloon 8i’s and would like to convert to electric. I looked at motors about 3 years ago and am not aware of what is new in the ebike industry. What would be better a mid drive or a rear wheel motor...

I am looking for some suggestions as to which kit I should get for my schwinn. I have talked to a few people who have said that the bike might not be a good fit for a motor. The bike rides really well and has a new set of tires, the breaks work just fine, and I have not had any problems with the...

So i got myself a new hyper bicycle with a new 66/80cc motor. After awhile of riding I felt that my chain had fully stretched so i tried to tighten it up again. While tightening I found that the slack of the chain would change to loose and then tight when I would spin the wheel so I figured...

I am new to motorized bicycle building. I just put together my first one and got it running last Friday or Saturday. Everything seems to be going fine with it except that it has started skidding when I release the clutch to start it. When the bike slows just a bit it turns over and starts. If...

I just ordered a grubee skyhawk 2012 GT5 66cc slant head kit from kingsmotorbikes.com and I plan to mount it on my roadmaster bike. I know I probably won't be biking on the sidewalks much if any after its mounted and running, but I tend to jump off curbs and small ledges less than a foot high...
