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.

I got the S18-MINI for my 14 year old teen boy, and he loves it. He rides it everywhere, on and off road, school, everywhere. It's a smaller fat tire electric mountain bike, but I think he can ride it even as he matures in size. I ride it just fine.
Great bike. It looks cool and has a powerful motor. I was a little worried about the size, but the bike fits perfectly. The adjustable seats allowed me to get that sweet spot for the most comfortable ride. I just love my new bike, can't wait for my upcoming bike trip.
