Ever get annoyed by the sluggish crawl of your mountain bike, wishing it had a little more pep to tackle hills and longer rides? I tossed this IMAYCC 100cc bike engine kit onto my trusty cruiser, and suddenly, pedaling up steep inclines felt like a breeze.

The engine’s power kicks in quickly, giving me a noticeable boost without feeling like I’m straining.

At first glance, it’s clear this kit is pretty comprehensive. The 2-stroke engine is compact but robust, with a sleek black teardrop fuel tank that fits snugly on my frame.

The engine itself is surprisingly powerful for a 100cc, pushing my bike to speeds up to 50 km/h on flat roads.
