Who is the L-91548 sized for?

It is a large frame with 28-inch wheels, so it suits taller riders, roughly those over 5 ft 10 in. Shorter riders will likely find the reach and standover too big.

Is full suspension worth it on an e-bike?

Yes if you ride broken pavement, gravel or light trails. Both ends soak up bumps and keep the wheels planted. On smooth city streets a rigid frame is lighter and simpler.

How does it compare with rigid commuter e-bikes?

It is more comfortable over rough ground thanks to the dual suspension and big wheels. Rigid commuters are lighter, cheaper to maintain and easier to store.

What should I check before buying?

Confirm the motor power, battery capacity and claimed range, since Flynama publishes little. Also check whether local shops can service the motor and battery.

Can I ride it on trails?

It handles gravel paths and light trails, but it is not a downhill or technical mountain bike. The suspension and frame are built for comfort, not hard riding.
