Is full suspension worth it on a bike like this?

It makes rough roads and light trails noticeably more comfortable. The trade-off is extra weight and some pedal bob, so it suits comfort-focused riders more than efficiency-focused ones.

What kind of riding is the Cityrun built for?

Light trails, gravel paths, fire roads and rough city streets. The 2.1-inch tires and 21 speeds handle mixed surfaces, but the suspension is not built for jumps or serious downhill riding.

How does it compare with a hardtail?

A hardtail is lighter, cheaper to maintain and pedals more efficiently. The Cityrun gives a smoother ride over bumps, which matters more on broken surfaces than on smooth climbs.

Do I need to assemble it?

Most bikes in this class arrive partly assembled, with handlebars, front wheel and pedals to fit. Check the listing for what assembly is required and have a shop check the brakes and gears before the first ride.

Are 2.1-inch tires wide enough for trails?

Yes for gravel, fire roads and light singletrack. They roll faster than wider trail tires but offer less cushioning and grip in loose or rocky terrain.
