Rad Power Bikes Radster Trail Review, 2024

Jun 2024

Price: $1999.00 | Model Year: 2024 | I’m blown away with the new Radster Trail from Rad Power Bikes. This is an exciting new model that is as versatile as it is powerful. From the frame to the motor to the wheel and tire choice, this is a terrific new model from one of the most popular makers of e-bikes.

Observations
  • I’m blown away with the new Radster Trail from Rad Power Bikes. This is an exciting new model that is as versatile as it is powerful. From the frame to the motor to the wheel and tire choice, this is a terrific new model from one of the most popular makers of e-bikes.

  • The Radster Trail rolls on 27.5 x 3-in. tires, what they call a mid-fat. I like the 3-in. width because it handles better than 4-in.-wide tires. Sure, it loses some cushion, but the narrower tire improves the maneuverability, whether on-road or off of it. While this isn’t an eMTB, it does have the ability to take in dirt roads and some natural surface trails. I ran the tires at less than 20 psi and that combined with the 80mm-travel fork gave me a very comfortable ride any time I wasn’t on asphalt.

  • According to Rad Power Bikes, this new motor still delivers a maximum of 750W, like other Rad Power Bikes motors, but they increased the torque in the motor by 54 percent to produce 100Nm of torque. What that means is that this thing really moves uphill. The narrower tire is substantially lighter than the 4-in. rubber we see on all-terrain models, and that almost certainly helps the Radster Trail’s acceleration.

  • This is a true Class 3 e-bike (but ships as a class 2), able to achieve 28 mph and it has both the power and the gearing necessary to reach that speed. Here’s another reason to like the 27.5 x 3-in. tires: This e-bike handles really well at speed. See Latest Price

Rad Power Bikes Radster Trail Review

Mar 2024 · Mike East

A new Powerful Motor, Safe Battery Technology, and All-Around e-Bike Versatility It's fair to say that Rad Power Bikes helped popularize fat tire e-bikes as we know them today. They don't seem to be content to churn out the same stuff year after year though. Our Rad Power Bikes Radster Trail review shows the company

Highs
  • Versatile and well-rounded, the Radster Trail is a compelling combination of comfort and capability that will appeal to a wide range of riders

  • One of Rad’s best motor experiences to date. The new 750W, 100 Nm of torque climbs hills easily, but it has very manageable power for any rider.

  • We love the enhanced fire safety with Rad Power’s new Safe Shield Battery, which features individual fire barriers for each cell, effectively preventing battery fire “runoff” and providing peace of mind.

  • Impressive range of over 75 miles on a single charge, achieved through the combinatin of a high-capacity 720Wh battery and an efficient torque sensor.

  • Better handling than most fat bikes. The 3”-wide tires are still very stable, yet feel livelier in turns than most 4”-tires.

  • Well-equipped for commuting, with integrated turn signals, front and rear lighting, fenders, and a rear rack, making it a practical choice for daily rides.

  • We like the increased e-bike security with the included proximity key fob (or backup password), providing an added layer of protection against unwanted use.

  • Braking felt solid thanks to the Tektro E350 Hydraulic Disc Brakes and 180mm rotors.

  • Practical range of gears. The large 50T chainring and 8-speed Shimano drivetrain worked well with the bike’s class 3 speed capabilities.

Lows
  • A bit nitpicky, but we would like to see an upgrade to the charger to at least three amps for faster re-charge times.

  • The front fender, resembling a short MTB-style fender, offers limited protection against water splashes, which might not be enough for commuters, potentially leading to a wetter ride in rainy conditions.
