Continental E.Contact road bike tire on a rolling resistance test machine

According to Continental, the E.Contact is a tire designed for large e-bikes or rental bikes. They claim this tire to have the highest puncture and cut protection while still providing a low rolling resistance thanks to its double layer of puncture resistance material. The E.Contact comes with the ECO 50 logo and the ECE-R75 certification which makes it suitable for high-speed e-bikes up to 50 km/h.

To achieve the highest puncture protection, Continental uses both a thick but soft layer of puncture resistance material together with a SafetyPlus Breaker which is a layer which is harder to penetrate, but much thinner. When examining the E.Contact, I immediately noticed this to be a very stiff tire. On top of that, the rubber compound itself also appears to be of a very hard kind. I definitely believe this tire to be hard to puncture, but is rolling resistance still acceptable?

All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs.

Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load.

Puncture resistance is good, but rolling resistance is very high. Continental's claim of offering the highest puncture resistance while still rolling easy isn't true. I really like Conti's road bike and mountain bike tires, but can't recommend using their touring bike tires as they don't impress. Using the E.Contact on rental bikes might be a good choice as I'm sure the hard compound and strong sidewalls will last for ages.

It gets boring, but just getting a pair of Schwalbe Marathon (read review) or Marathon Plus (read review) seems to be the easy choice in the tour/e-bike category. Those tires provide a good puncture resistance and a much lower rolling resistance.

RATING: 2.0 / 5
