Owners of 20 inch compact, cargo or folding e-bikes who want comfort, puncture protection and night visibility.
Small wheels ride harshly on skinny tyres. The Schwalbe Big Ben Plus fixes that with big air volume, acting like built-in suspension over potholes, tram lines and kerbs.
This 20 x 2.15 inch (55-406) version has a 3 mm GreenGuard puncture protection layer, reinforced sidewalls and a reflective stripe on each side. It is ECE-R75 approved and E-50 rated, so it is cleared for e-bikes up to 50 km/h, and it carries up to 95 kg per tyre.
It is a common fit on 20 inch cargo, compact and folding e-bikes. The wire bead keeps it tough and good value.

Reflex sidewall
A reflective stripe on each sidewall makes the bike visible from the side at night.
Great for
Maybe not for
Fits 20 inch (406 mm bead seat) rims only, not 451. Use a 20 inch tube sized for tyres around 2.15 inches wide. Check frame and mudguard clearance for a 55 mm tyre.
406 or 451?
There are two 20 inch rim sizes. This tyre is 406, the common size on cargo, folding and kids' bikes. If your old tyre says 451 or 20 x 1 1/8, it will not fit, so check the sidewall first or bring the wheel in.
Pressure
Run it between 2 and 4 bar. Loaded cargo bikes want the higher end, lighter riders can drop it for more comfort.
