How far can it really go on a charge?

The claimed maximum is 65 miles per charge from the 48V 20Ah battery. Expect less in cold weather, on hills, or when relying heavily on the motor rather than pedaling.

Is the battery certified and replaceable?

Yes. The 48V 20Ah lithium battery is UL2849 certified and removable, so it can be taken off for charging or swapped for a spare.

Soonway rates it for slopes up to 30°. The 749W motor and fat tires help on gravel and loose ground, but long, steep climbs will drain the battery faster.

How does it compare with larger fat-tire e-bikes?

Its 16-inch wheels are smaller than the 20- or 26-inch wheels on most fat-tire rivals, which trade some rollover comfort for a lower, more compact stance. In return it offers NFC unlock and a UL-certified removable battery.

How much assembly is needed?

It ships 90% pre-assembled. Expect to fit the front wheel, handlebars, pedals and check the brakes before the first ride.

Adults who want one bike for commuting plus sand, snow and gravel paths, and who like keyless NFC or password start. Riders wanting high pedaling speeds or light weight should look elsewhere.

Our take on the Retro S9-2 Adult Electric Bike

The Soonway Retro S9-2 is a fat-tire electric bike for adults with a 749W brushless motor, a 20 mph top speed and a claimed 30° climbing ability. A removable 48V 20Ah UL2849-certified battery gives a claimed range of up to 65 miles per charge. It rolls on 16"×4.0" fat tires with a carbon alloy frame and hydraulic front fork, and adds front and rear disc brakes with EABS, bright lighting, and NFC and password unlock. It suits riders who want one bike for gravel, snow, sand and commuting, though its 16-inch wheels and single-speed-style simplicity put it behind geared rivals on long road rides.

Pros

749W motor with a 20 mph top speed and 30° climb rating
Removable 48V 20Ah battery, UL2849 certified
16"×4.0" fat tires for traction on loose and soft ground
Hydraulic front fork and carbon alloy frame
Front and rear disc brakes with EABS and bright lights
NFC and password unlock; ships 90% pre-assembled

Cons

Small 16-inch wheels roll slower and handle bumps less well than larger fat-tire bikes
65-mile range is a best case; heavy riders and throttle use cut it sharply
No gearing listed, so pedaling past 20 mph is limited
Fat tires and a 20Ah battery make it heavy to carry or store
