$89.99
perfect for giving your motorized bike more power and that awesome throaty sound, the BBR Tuning High-Performance F2 Thrust Exhaust Muffler is what you need for optimum torque and speed out of your 2-stroke engine. Its baffle-less design uses an expansion chamber to circulate the exhaust around and out of the muffler for a smoother ride, while a long pipe lets you expel exhaust faster and more efficiently. This results in increased torque and higher top speeds. With 40mm mounting stud spacing, this muffler is compatible with nearly any 66/80cc 2 stroke engine around. So when the exhaust from your motorized bicycle engine kit is holding you back and performance mufflers aren't giving you maximum power, this High-Performance F2 Thrust Exhaust Muffler will have you screaming down the track. The BBR Tuning High-Performance F2 Thrust Exhaust Muffler is perfect for giving you more power and sound out of your 2-stroke motor. Made for racing and performance engines, you can forget that old exhaust you’re using and replace it with the Thrust muffler for better power and speed. Instead of using a baffle that will hinder your performance, the BBR Tuning F2 Thurst muffler makes use of its baffle-less design to expel more exhaust from your motor. This exhaust utilizes expansion chamber technology to circulate the exhaust around the chamber and out of the muffler for a smoother ride. Its length will also let you expel exhaust faster and more efficiently, just like a stretched or long-shot muffler would. If you’re tired of your expansion chamber always hitting your pedals or your stretch muffler hangs too low for your taste, the BBR Tuning High-Performance Thrust Exhaust Muffler is what you need. The Thrust exhaust combines the exhaust capabilities of a long shot muffler, the smoothness of an expansion chamber, and the length and efficiency of a stretched muffler. If you’re tired of your performance engine not getting the power you want, the BBR Tuning High-Performance F2 Thrust Exhaust Muffler is exactly what you need. Specifications: 29in. from exhaust tip through the mount (including bend at the mount) 40mm Mounting Stud Spacing Color: Chrome and black Compatible with 66/80cc 2-stroke bicycle engine kits (can work with 48cc 2-stroke mufflers with 40mm exhaust stud ports) Package Includes: 1x Chrome the BBR Tuning High-Performance F2 Thrust Exhaust Muffler 40mm Muffler Gasket Mounting brackets and hardware Note: This muffler will raise slightly upward and over the magneto/drive sprocket side cases, going to the back of your bicycle.

Wheel Master Motorbike Mag Wheels - Gas Bike Wheel Set
$199.99
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 Wheel Master 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 6x stud ports to support nearly any disc brake assembly- even the rear wheel. And did we mention that each rear wheel comes with a 44 tooth motorized drive sprocket? Yup, and it’s disc brake ready, 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 +$90 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) Once through, 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. Specifications Alloy mag wheels with a flip flop style hub with fixed 44T cog for gas powered bicycles Suitable for tires between 1.75 and 2.2 inches wide Multi-speed or single speed freewheel compatible Machined brake track Inner rim width: 17mm Outer rim width: 27mm Axle length front: 155mm Axle length rear: 180mm with Schrader valves Brake Compatibility: Disc Brake and Caliper Brake Bicycle Engine Sprocket Size: 44 Tooth

Buyer accepts responsibility for any and all vehicle operation that may lead to personal injury, economic loss, social distress, other losses, costs and damages. Seller is not responsible for injuries and/or damages resulting from operating this motorized bicycle or bicycle engine kit. Upon purchase, the buyer agrees to comply with local requirements and restrictions in areas where EPA approved engines are allowed on public roadways. Otherwise, the riders agrees to use products for racing (closed-course competition) only and not for on/off public roads. Disclosure of accurate engine size: While we have chosen to use the long standing factory branding engine size of "80cc", the true displacement of the bicycle engine is 66cc. Down through the years China bicycle engine manufactures have advertised their biggest engine as 80cc, therefore we have listed them in the same way on our website. However, the bore and stroke of an 80cc being 47x38mm equals 66cc. Therefore the true displacement of the 80cc bike motor is 66cc. In the west, the volume of a cylinder is calculated by using the formula Volume = Pi x Radius Squared x Stroke. However,in the east the displacement of an engine includes the area of the cylinder head's combustion chamber as well as the volume of the cylinder. Therein lies a discrepancy between measuring standards by the manufactures in China with those in the United States. However, all "80cc" engine kits on the market today are actually 66cc in displacement size if measuring by US standards.
