I took the highly reviewed Rad Power Bikes Radster Trail off-road to test its quiet 750W motor and fast-engaging torque sensor. While it is heavy at 77 pounds, it powers up 30-percent grades with ease.

The good:
- Quiet 750-watt rear hub motor that avoids the classic loud whine.
- Torque sensor engages immediately on loose gravel with zero delay.
- Carried me up a 25 to 30 percent grade hill test at 9 mph without struggling.
- Easily changeable class settings to swap between Class 1, 2, or 3 depending on local laws.
- High 370-pound payload capacity with a 55-pound rear rack limit.
- NFC card system makes securing and unlocking the bike incredibly easy.

The trade-offs:
- Weighs in at a hefty 77 pounds, which is absolutely not lightweight.
- The 80 mm front suspension is too rough for anything beyond light green or blue-rated trails.
- The front aluminum fender is quite small.

Specs:
- Motor: 750-watt rear hub
- Battery: 48-volt, 15 amp-hour
- Top Speed: 20 mph throttle, 28 mph pedal assist
- Range: 65+ miles (over 70 miles possible slow on paved trails)
- Charge Time: 6 to 7 hours
- Weight: 77 lb
- Payload: 370 lb
- Rear Rack Limit: 55 lb
- Suspension: Front fork, 80 mm travel
- Tires: 27.5 x 3 inch all-terrain
- Brakes: Tektro hydraulic (mineral oil)
- Gears: 8-speed Shimano Altus

Review:
Overview

There is a lot of buzz surrounding the Rad Power Bikes Radster Trail, and I wanted to see exactly why it is one of the most talked-about e-bikes right now. Rad Power Bikes has been around since 2007, and their lineup has evolved significantly over the years. This particular model is a mid-step trail bike built with a classic dual-bar frame and a beautiful green paint job that I absolutely love. 

It currently sits at a recently dropped price of $1,999, making it an intriguing option for riders who want power mixed with utility. It features an IPX 6 waterproof rating, so you do not have to panic if you get caught in the rain. Overall, it is built to handle dirt paths and daily commuting, all while carrying a ton of cargo.

Real-World Performance

The standout feature for me is the torque sensor. When I took it climbing on loose gravel, there was zero delay. As soon as I put pressure on the pedals, the motor engaged, which is exactly what you want when navigating off-road terrain. I also put it through my standard hill test, taking it up a 25 to 30 percent grade. It had absolutely no problem making the climb, holding a steady 9 mph by the time I crested the top.

Speed-wise, the half-twist throttle tops out at 20 mph. If you start pedaling, you can easily push the bike to 28 mph with a normal cadence. As for range, I did not do a full drain test, but the 48-volt 15 amp-hour battery is standard for this class. Tests from other reviewers show it can hit up to 75 miles on pedal assist level 1 at 10 mph, or roughly 35 miles on level 5 at 18 mph. If you ride slowly on paved trails, getting over 70 miles is definitely achievable.

Taking it off-road is fun, provided you choose your trails wisely. It thrives on light dirt paths and loose gravel. However, if you are looking to hit insane mountain bike trails, do not buy this bike. It can climb anything, but the 80 mm of front fork suspension makes things too bumpy for anything beyond a green or light blue-rated trail.

Design & Build Quality

A lot of people claim this bike is sleek and lightweight. I have to strongly disagree with the general public on that one. At 77 pounds, it is a heavy, full-size e-bike. The tradeoff for that weight is utility. It boasts a massive 370-pound payload capacity, meaning you could easily use it as a cargo bike, especially with the rear rack that can hold 55 pounds.

I tested the larger size frame, and at 5-foot-11, I found the geometry extremely comfortable. It offers a very upright riding posture with only a slight bend in the back. A big reason for that comfort is the mini-BMX-style swept-back handlebars and a stem with about a 2-inch rise. You do not have to reach far to grab the lock-on wingtip grips.

Fit and finish are solid. The welding scars are visible but not overly aggressive, and the aluminum fenders are a nice touch, even though the front one is a bit small. It rolls on 27.5 by 3-inch all-terrain tires, and the saddle is appropriately sized for trail riding without being overly cushioned.

Key Features

The power comes from a 750-watt rear hub motor that is surprisingly quiet. I love a quiet ride, and this completely eliminates that classic, loud motor whine common on many e-bikes. The control pad gives you five levels of pedal assist, and if you hold the M button, you can access advanced settings to easily change the bike between Class 1, Class 2, or Class 3 limits depending on your local laws.

Security and safety features are a major highlight. You can turn the bike on and off simply by tapping one of the two included NFC cards against the display. It also features a bright, automatically engaging headlight and built-in turn signals that display on both the screen and the taillight.

Stopping power is handled by Tektro hydraulic brakes running on mineral oil, complete with motor cut-offs. Whenever you pull the brake levers, the taillight flares up to warn riders behind you. Finally, shifting is managed by an 8-speed under-the-handlebar trigger shifter paired with a Shimano Altus derailleur.

Who It's For

I recommend the Radster Trail for commuters and casual trail riders who want a quiet motor, massive payload capacity, and immediate power delivery from a torque sensor. If you need a bike that can easily tackle steep 30-percent grades and haul a lot of gear comfortably, this is a fantastic choice.

Who Should Skip It

If you are looking for a truly lightweight e-bike that you can easily carry up a flight of stairs, skip this one, as it weighs 77 pounds. You should also look elsewhere if you want to tackle aggressive, heavily rooted mountain bike trails, as the basic front suspension will bounce you around too much.

How It Stacks Up

Within the highly competitive $2,000 e-bike market, the Radster Trail features a fairly standard 48V 15Ah battery size. However, it separates itself with premium touches that many competitors skip. The integration of NFC card security, built-in turn signals, a remarkably quiet motor, and the ability to easily toggle between Class 1, 2, and 3 speeds right from the display give it a major edge over basic hub-motor fat tire bikes.

Final Verdict

The Rad Power Bikes Radster Trail is incredibly popular for a reason. For $1,999, you are getting higher-end hydraulic brakes, fantastic climbing power, an immediate torque sensor, and a beautiful design. Just keep the heavy weight in mind, stick to moderate trails, and you will have an absolute blast riding it.
