Gas bike conversion kit


The Spring Loaded Idler Pulley will maintain consistent pressure on the chain to maximize performance. It will reduce stress on the chain and keep a consistent tension through any ride. This aftermarket performance upgrade comes with all the hardware for installation. Compatible with all 2-stroke 48cc/50cc/66cc/80cc engine kits as well as 4-stroke 50cc engine kits.


We carry the best gas bike conversion kits, frames and parts. Do it yourself or have us do it. Either way, a kit can be a great option. We have 2-stroke and 4-stroke kits, including the quick-install friction drive.


Installing an expansion chamber on your gas bike has many benefits. This Expansion Chamber with Muffler will enhance your power output by expanding the volumetric efficiency on your 2-stroke bike engine. In addition to adding a boost in the top end speed, this type of muffler improves the use of any left over energy from the burnt exhaust exiting the cylinder. This helps aid the filling of the cylinder for the next cycle, and all is done with a muffler to tune the sound of the exhaust. The end result is better fuel efficiency, more top-end, smoother throttle response and a quieter exhaust note.

Standout Features:

  • Mag wheels - no more broken spokes
  • Built-in large capacity, gas tank
  • Durable sealed wheel bearings
  • Expansion chamber and reed valve option

Tired of truing your motorized bike wheels every fifty miles or so? Let’s face it, even the heaviest-duty spoked wheels still need plenty of maintenance and eventually need to be rebuilt. But with the BBR Tuning 26 Inch Heavy Duty Motorized Bike Mag Wheel Set you’ll be able to ride longer and faster with more security than regular bike wheels ever gave you.

These alloy wheels are meant for heavy riding. Made of heavy duty alloy metal, there are no spokes to worry about other than the 6 big fins that cut through wind a WHOLE lot better than spoked wheels. Unlike standard bike wheel hubs with multiple pieces, these hubs consist of a set of bearings and a thick, sealed alloy center. Most wheels give out easily because of the multiple pieces that combine to make the hub, but because these wheels have no spokes and a solid hub, there’s no need to rebuild your wheels after long rides at high speeds.

Each wheel is disc brake-ready, with six stud ports to support disc brake. The drive gear is mounted on the rear wheel, disc mounting holes, for secure transfer of power. The rear wheel comes with a 44 tooth motorized drive sprocket too. That means you don’t have to use those old, ratty rag joints to mount your rear sprocket, nor do you have to spend added dollars on a sprocket adapter and the compatible sprocket. All you need is the engine chain and your motorized wheels are almost complete.

Of course, any tough wheel needs a strong tire. These single-walled wheels have tire lips big enough to fit fat, knobby 26” tires with lots of grip and tubes that hold lots of air. As far as installation, it couldn’t be any easier.

If you’re using disc brakes, install the disc of your disc brake assembly on to the studs of the wheel and fasten them out (if you’re using caliper brakes, just tighten down the disc brake studs on the rear wheel to fasten the rear sprocket to the wheel). Install a single-speed freewheel on to the rear wheel and lock it on to the wheel. Line your wheel with tire liner, then install your tubes and tires as you would normally. Take one nut and one spacer off of each wheel axle and insert the axle through the wheel’s bearings (leaving a spacer and nut on the other side, centering the wheel in the frame). Once complete, reinstall the spacer on to the open side of the wheel. Install the wheels on to your bike, fasten down the remaining nuts on their axles, and align your chain. Now you’re ready to ride!

So when you’re ready to make your motorized bike a mad man on the tracks as well as the trails, step up to the BBR Tuning 26 Inch Heavy Duty Motorized Bike Mag Wheel Set and feel what you’ve been missing.

Tired of looking for the right frame for your bike engine kit? If you just want to bolt up and ride without messing with zip-tie's or fabricated mounts, then the BBR Tuning 26" Motorized Bicycle Frame is the frame you've been looking for. Ditch that old, clunky tank- this frame's got a 2.4L gas tank built right in, with an easy-to-use twist gas cap. The frame also cleans up your cables with cable ports running along the center and bottom of the bike, eliminating the need for ugly zip-tie's that can break loose. It's also center-pull brake ready with mounting studs for the brake arms. Your completed bike will also weigh far less than a conventional steel frame. With a front motor mount that can adapt to nearly any bike engine around, the BBR Tuning 26" Motorized Bicycle Frame is a lightweight, high quality bike frame just waiting for your next build!
