Trek’s Domane+ e-road bikes have been powering through the launch editions lately, starting with the lightweight Domane+ LT. Then they added a Project One custom option for it. The more powerful Domane+ HP offered a big boost of newtons, and all of those used carbon fiber frames.

Now, the Domane+ ALR packages the lighter Fazua motor system into a sleek alloy frame that drops the price without dropping the best features…

The Alpha Aluminum frame is built around the same Fazua Evation drive system that powers the lighter LT model. That means you can remove the entire drive pack (battery + motor) quickly and easily, leaving you with a regular unassisted road bike without any added drag.

The Fazua motor kit is light on its own, and used for bikes that want some assist without the brute power of bigger motor and battery drive systems. It has a 250Wh battery and will assist up to 20mph in the U.S., and 25km/h in Europe.

It also removes most of the added weight, with only a bit of extra frame material giving any indication this was an e-bike.

Controls are integrated into the top tube, leaving your handlebars clean of any remotes or displays. The shifting and gearing is mostly Shimano 105, with FSA’s e-bike compatible double chainring setup at the cranks:

While it looks like a road bike, it can handle more. There’s clearance for 700×38 tires, and it’s based on their endurance geometry. And with the ability to assist for up to 65 miles, its range can help you tackle those longer rides, too.

    • If you click through the link, you’ll see it’s US$4599. So about as much as the un-electrified aluminum Domane plus a pretty nice electric scooter.

  1. I still do understand the reasoning behind the 20 mph cutoff for a road oriented bike that is targeted for US sales. Make it a true class 3 with a 28 mph assist and then it’s a better option.

    • for a fazua motor 20mph is pretty ok i guess. Even for a full bosch shimano motor i think it’s ok, on the other hand in europe 25 really suck.

      • Most of Fazua’s marketing spiel highlights assist going uphill. Not every bike ride is up mountains. The maximum assist is 250 watts with the Evation motor, so in theory you not going to get much more than a few mph over 20. I think it makes sense in the UK, but not so much is the US.

  2. Does anyone take advantage of the “removable” feature? It seems like another product manager check box. Wouldn’t you just run it in the lowest assist mode.
