Looking for an easy way to get around town, well a motorized bicycle is the way to go. Including everything required for the assembly of a motorized bike, the Switz Cruz + 4 Stroke Chain Drive Motorized Bike DIY kit is an economical and affordable choice. With a HuaSheng 49cc pull start bicycle engine, upgraded hush muffler, a heavy-duty bicycle chain, and a high-performance carburetor, the Micargi chain drive motorized bike is decked out with a great range of components.

Assembling a bicycle from scratch using random parts can be very difficult and extremely frustrating, not to mention expensive. Not all bicycle frames are suited to fit any motor type or size. The Switz Cruz + 4 Stroke Chain Drive Motorized Bike DIY kit comes complete with carefully selected components to ensure 100% compatibility with no “extra” parts. With just a few basic tools and general knowledge of how mechanical parts work together, riders will be able to fully assemble a reliable and hardworking motorized bike that is perfectly suited for cruising.

The Switz Cruz 26" Men's Beach Cruiser comes with a chain-driven 4-stroke motor. The chain drive system is still a lot more common than some of the newer drive technologies and has long been used for powering a traditional pushbike. This means that the Switz chain drive motorized bicycle will be easier (and cheaper) to service than a belt-driven system.

The Switz Cruz is not any ordinary beach cruiser, it's highly upgraded with an oversized padded saddle, classic fenders, and an adjustable oversized handlebar. The unique frame style of the Cruz allows for a high degree of adjustability to accommodate almost any rider 5'2'' and above. This bike is specifically engineered for comfort and style with it's ultra-smooth 2 inch wide tires with a comfortable tread.
