My wife has a Scott, essentially a Contessa with a Bosch crank motor. Very heavy thing, bloody hard work with no assistance, but even with assist on progress surely depends on your effort. We don’t do a lot of trail centres, but it’s been fine round Rothie, up to Einich, in Inshriach and up the Corbett behind Kingussie, as well as onroad. Lets us ride together, which would be harder without assist, and is heling her recover from skiing injuries.
Last year, the Trek Powerfly 9 LT was one of the only ebikes with geometry and handling that came close to a modern enduro bike. For 2018, Trek has built on that winning formula with new frame. It’s lowered the battery in the downtube, while adding a stiffer Fox 36 fork, more powerful SRAM RE brakes and a stronger Bontrager wheelset. All welcome improvements to a really capable bike. The price has also crept up to reflect the changes. The biggest transformation however, is that Rocky Mountain has raised the ebike bar to a new high with the Altitude Powerplay.
This bike is not as premium as the more expensive offerings but it is very durable and it will get the job done. If you're new to E-bikes its a great entry level E-bike. Its weakness can be its pluses its understated look makes it blend in with other bikes and when it is locked up it may not be as prone to get stolen as the more expensive eye-catching designer bike.
