I especially liked how well it fits bikes with 26-28″ wheels, as long as you check for the required clearance—it’s a perfect upgrade for mountain or cruiser bikes.

Fueling is easy with the included 3L tank, and the fuel economy at around 2.5L per 100 km is pretty decent. Just remember to break in the engine with 16:1 fuel mixture first, then switch to 20:1 after a few hundred kilometers.
