Review: Nice for the price - 5 stars for the price. How well it fits depends on how good you at bending with a torch. Will need some deburring at the flange. Fits my 36v/50cc mototec conversion perfectly
Review: Great Replacement for Pocket Bikes - This is a solid replacement for the stock pocket bike exhaust. Installation is easy and we were able to do it without having to disassemble the bike! And that was a first. I usually have to remove the faring and gas tank or the fork. It comes with gasket and hardware, but did not include lock washers, which are critical for preventing the screws from backing out from engine vibration.

## Questions & Answers

**Q: will this fit a motorized bicycle?**
A: no

**Q: Does this fit mototech 49cc gt? Pocket bike**
A: yes

**Q: Will this fit a mototec 50cc demon?**
A: Not sure, but if you study the picture and make sure your bolt holes are the same you can bend this exhaust pretty easy to get it to line up. Mine would have come out my seat if I didn't bend it to fit. Clamp down 1 side of it and stick a pry bar , pipe, tire iron in there to bend it just go slow so as to not over bend it

**Q: Why wont the items i want ship to my location**
A: Please concact with Amazon service

### ⭐⭐⭐⭐⭐ Great Replacement for Pocket Bikes

### ⭐⭐⭐⭐ It works on my super scooter
*by C***W on October 2, 2023*

It improved midrange power but I lost some top end. That said I’m very pleased with the results. Just be aware that this is loud so take that into consideration you don’t want to piss off the neighbors. About the super scooter it started out as a Razor metro Eco-smart. I replaced the 500 watt electric motor with a 47.2cc motor. I installed a 450 watt electric motor on the front. It’s a 2 wheel drive hybrid now. I changed the drum brake to a 180mm disc and added rim brakes. For comfort I added front suspension, suspension seat post and a comfortable leather seat. I’m 6’1” 175 pounds and this thing will do 20 mph going up an incline.
