Product Dimensions and Specifications

The 48cc engine kit is about 8.5" height 7" length 5" width. The bike engine kit fits on standard, male frames with tubing of 25mm to 29mm in diameter. Larger frame sizes require drilling into bike frame with a stationary bolt and use the universal face plate to mount the front of the engine.

20 to 30 mph depending on the gear ratio and weight

Fuel Economy: approximately 100-150 miles per gallon

The engine chain does not interfere with your current drive chain and peddling because it rides on the opposite side of the bike sprocket.

Product Requirements

Installation is a breeze! The rider only needs some basic hardware skills, tools, and around 2-3 hours for installation and fine-tuning adjustments (Note: Seller is not responsible for misuse or this kit or any warranty after installation).
