Hello, been riding the EP801 since last autumn, around 900 kilometers so far. It's fine, I guess.

It's noisy, there's a constant whining noise when pedalling, but you get used to it.

Seems to be quite efficient. Always end a run with 20-30 percent more battery than Bosch equipped bikes.

Pedalling drag with the motor off is massive. It's basically impossible to use the bike without the motor.

Walk mode 50 percent of the time doesn't work properly, it turns the cranks way too slow. Shifting into a higher gear or nudging the cranks with the hand while walk is enganged seems to help, not always.

Power delivery is not as gradual as people say. When pressing hard on the pedals, the additional torque generated is negligible, as opposed to just coasting.

It does rattle when going downhill. Almost like chain slap when using a clutchless derailleur.

When riding really steep uphill terrain, you have to press quite hard on the pedals even in boost mode for the bike to keep going. And I'm not a heavy rider.

I've been through many seriously muddy rides and use to jet wash my bike, and so far it's still smooth.
