AOSTIRMOTOR S18-MINI DESCRIPTION
The Aostirmotor Ebikes S18-MINI is truly unique. It's a full-suspension mountain bike with 20" x 4" fat tires, perfect for any off-road adventure.
When I first tried the S18-MINI, I was blown away. I'm a big guy, so I was worried that this bike might be too small for me or might lack the kind of power I'm used to, but I was wrong on both counts. The 500W rear hub motor featured on the S18-MINI has tons of power and torque, and even on the roughest terrain, the full-suspension frame really absorbed the shocks.
Whenever I test a new ebike, the first thing I do is ride it like a conventional bike with the electronics turned off. I found the 7-speed Shimano Sunrace gears to shift smoothly, and the bike handled exceptionally well.
But then I turned on the power and checked out the pedal assist system (PAS), which was remarkably responsive for an ebike with a cadence sensor. I also found the twist throttle to be easy to operate and fun to use.
