Proud Wisconsin brand Trek Bikes has been a leading innovator in the cycling market for decades. Now they’ve shifted their focus to making quality electric bikes for every rider. Designed in the US and built in China, every Trek bike comes with the coveted Trek warranty and guarantee. Though Trek offers a full range of electric bikes, we’ll be focusing on the Trek Powerfly 5.

Priced at $4,199.99 and available in two colors (red/black, green/charcoal) the Trek Powerfly 5 is an electric mountain bike built with premium Bosch components. A highly versatile ride, it boasts a robust aluminum frame available in four size options (S, M, L, and XL). The frame offers durability while protecting the components inside, including the interior cabling system and battery. Unlike similar e-bikes, the Powerfly 5 has a clean aesthetic and easier handling due to a lower overall weight. This is a very quiet ride which many appreciate.

In terms of battery, Trek wanted to include a fully integrated battery that is protected from dirt and grime, thus extending the overall battery life. The battery utilized is a Bosch Powertube 500Wh with the removable portion located on the downtube. Like every Powertube battery, you garner an impressive range of up to 80 miles in Eco mode and 37 miles in Turbo mode. Once your battery is drained, it can charge in as little as 3 hours on the fast charger.

Of course, Trek didn’t forget about adding enough power to boost your ride. Thus they included a Performance CX motor that pairs perfectly with the Powertube. The mid-mount motor on this bike was designed with off-road riding in mind. Ideal for an electric mountain bike. With 75Nm of torque, you can tackle even the most challenging trails while reaching speeds of up to 15 MPH.

The motor system also includes a Bosch Purion controller that lets you achieve your ideal power range with 5 assistance modes. Performance is also enhanced by the 10-speed Shimano Deore drivetrain. Smart wheel size technology, means you’ll always get the right size tires for the frame you choose. Tire sizes range from 27.5”x2.35” (Small) to 29×2.30” (M, L, XL).

Overall, the Powerfly 5 is a great choice if you want to spend a little more on an electric mountain bike that really works. While you may be able to find cheaper options from Rad or Hyper, you won’t be getting the high-end components included in the Trek.
