Perhaps the most disruptive brand and bikes to hit mountain biking in decades, Amflow arrived with a bang a few years ago and have gone from strength to strength since completely re-defining what people have come to expect from an E-Bike. Now into their second generation of bikes, the 150mm travel PR is the removable battery model. Want to run multiple batteries throughout the day, or can't easily store your bike near AC power? This is your model and at 2.9kg (with complete bikes moving in around 22kg), the frame is still competitively light, especially compared to other swappable battery bikes.
Like all Amflow bikes, motor power comes from the benchmark Avinox M2S, which pumps out a whopping max 120Nm of torque and 1300W of continuous power, with even more available from the 30 second Boost mode. Despite all the power the motor only weighs 2.6kg and is packed into a small form factor, keeping a clean look to the bike. Fully user tuneable via a simple app, it can deliver anything from long range low power rides to super fast power hours or the ability to ride up previously impossible climbs. Default battery size is 800W and the supplied 12A fast charger will push 80% charge back in just under an hour and a half.
When it comes to geometry, the PR has a whole load of adjustment baked in letting it cover many bases. A default reach of 475mm, head angle of 64.5 and wheelbase of 1256mm on a Large are all sensible modern numbers but the scope to change them is massive. BB can be dropped by an extra 14mm via one flip chip, and the chain stays can swap between 440mm and 452mm via another. The bike also comes with an angleset headset opening up further opportunities to create everything from an upright an comfy tourer to a super low and slack trail rocketship.
Integration is another areas where Amflow have pushed things forward. With the bikes able to track rides, link to your GPS or action camera, set their assistance based on heart rate and handle gear changes while coasting, their functionality is unmatched in the marketplace right now.
You might think that all that tech would result in a massive price tag, but you would be wrong. The PR is not just one of the most advanced bikes on the market, but also one of the most reasonably priced.
