RadRunner Plus (2025) YouTube Review: See It In Action
Specs and pictures only tell part of the story. To see how the RadRunner Plus actually handles in the real world, watch our complete video review below. We put it through its paces, covering everything from a detailed walk-around to a hill climb test with a passenger.
What Makes the RadRunner “Plus”?
The “Plus” in the name signifies three key upgrades that transform the base model into a more capable and comfortable machine right out of the box.
First is the front suspension fork. The Exsho suspension offers 65mm of travel, which makes a noticeable difference in ride quality by smoothing out bumps and cracks in the road. Second is the inclusion of a 7-speed Shimano Altus drivetrain. This is a crucial upgrade for anyone living in an area with varied terrain, as it provides the necessary gears to tackle hills without over-exerting yourself. Finally, the RadRunner Plus comes standard with the full passenger package. This includes the padded rear seat, retractable footpegs, and a protective wheel skirt, making it instantly ready for family adventures or carrying a friend.
Frame, Sizing, and Comfort | RadRunner Plus (2025)
Offered in one size and one color, the aluminum step-through frame has a very low 15-inch standover height makes it exceptionally easy to get on and off. This accessible design, combined with adjustable BMX-style handlebars, comfortably fits riders from 4’11” all the way up to 6’2″.
A unique feature of the RadRunner line is the moped-style saddle. It allows you to lower it completely for a casual, relaxed cruise or raise it for proper leg extension when you want to pedal more efficiently. While this design is versatile, some riders may find the seat a bit firm for longer rides. The combination of the upright riding position, front suspension, and wide tires makes for a generally comfortable experience.
Specs and Components | RadRunner Plus (2025)
Powering the ebike is a 48V, 13Ah (624 Wh) battery that is UL 2271 certified and potted with Rad’s Safe Shield technology for thermal management. The entire electronic system is certified to UL 2849, offering significant peace of mind. The color LCD display is easy to read and includes handy features like a passcode lock and a USB-C port for charging your phone.
Performance Tests: Rad Power Bikes RadRunner Plus (2025)
This section breaks down how the RadRunner Plus performs in key real-world scenarios. We tested the 750W motor, its cadence-based assist system, throttle-only performance, and drivetrain to see how the bike handles everything from accelerating from a stop to climbing steep hills. The following results show what you can expect from the bike’s capabilities.
Throttle-Only Acceleration
The half-twist throttle will engage from a stop and accelerate smoothly to its 20 mph top speed. The power delivery is programmed for a gradual ramp-up rather than a sudden jolt, which helps you maintain control, particularly when starting with a passenger or heavy load on the rear.
Riding with Pedal Assist
The 5-level pedal assist system (PAS) is paired with a cadence sensor that delivers consistent power when it detects the pedal cranks turning. How much assistance the motor provides is dependent on the PAS level you choose. The power engages after approximately a quarter turn of the cranks. Each level provides a distinct level of assistance:
- PAS 1-2: These lower levels are suitable for low-speed cruising, maintaining speeds of approximately 10-12 mph. They are useful for navigating crowded paths or for riders who prefer to cruise.
- PAS 3-5: The upper levels provide progressively more power, allowing the rider to reach and maintain the 20 mph top speed with less physical effort. The 7-speed gearing provides an adequate range to prevent “ghost pedaling” at higher speeds.
Hill Climb Test
- Throttle Only: The bike was able to ascend the entire hill using only the throttle, holding a minimum speed of 13 mph. This indicates the motor has sufficient torque for moderate inclines without pedal input.
- With Pedal Assist: Utilizing the pedal assist system in a low gear makes climbing significantly easier. In the mid-range PAS levels, a speed of 8-10 mph was easily maintained. For maximum climbing power, the throttle can be used in conjunction with any PAS level to ensure the motor is delivering its full output.
RadRunner vs RadRunner Plus vs RadRunner Max 2025: A Comparison
Here’s where things get interesting. You might think the RadRunners are all cut from the same cloth, but that’s not the whole story. Each one is actually built on a different frame with its own payload capacity. It’s the details, both big and small, that give each model its own personality. We’re talking about everything from the type of kickstand they use to the major upgrades like suspension, gears, and whether the passenger kit is included. These differences, combined with varying performance tiers and the option to add a Range Extender battery to the Plus and Max models, result in three distinct packages for different types of riders.
RadRunner: The No-Fuss Workhorse
The RadRunner is the straightforward, get-the-job-done model. At $1,499, it’s the most affordable of the bunch and is built for simplicity. With a single-speed drivetrain and a rigid steel fork, you never have to think about shifting gears, which keeps maintenance low. It has a respectable 65 Nm of torque and a 320 lb payload capacity. While it has the same Gemma hydraulic brakes as the Plus, it comes with the basics elsewhere: no fenders, a simple integrated taillight, and a lower-lumen headlight.
Who is it for? The RadRunner is for the rider who values simplicity and a lower price point. If you live in a mostly flat area and want a dependable utility ebike for errands that you can customize over time, this is your starting point.
RadRunner Plus: The All-Inclusive Comfort Cruiser
The RadRunner Plus, at $1,799, is the “just right” model that comes loaded with upgrades for comfort and versatility. The motor gets a torque boost to 70 Nm, and the payload capacity increases to 350 lbs. The biggest change is the 7-speed Shimano drivetrain, a significant advantage for anyone who lives in an area with hills. You also get a front suspension fork with 65mm of travel that smooths out bumpy roads. It comes with full-coverage fenders and the complete passenger kit pre-installed, making it ready for family adventures right out of the box. Plus, if the standard 55-mile range isn’t enough, it’s compatible with Rad’s Range Extender to push your adventures even further.
Who is it for? This is a good choice for families or anyone who wants a do-it-all utility bike without the hassle of buying and installing accessories. If you want to carry a passenger, tackle varied terrain, and enjoy a more comfortable ride with the option for more range, the Plus is worth considering.
RadRunner Max: The High-Performance Commuter
The RadRunner Max is built for the rider who wants higher performance and more features. For $2,299, the headline upgrade is its Class 3 capability, reaching speeds up to 28 mph. The motor produces 90 Nm of torque, and the frame is built to handle a 420 lb payload. It also features a larger, semi-integrated 14 Ah battery for more range, which can be supplemented with the Range Extender for a massive travel distance.
The tech is also upgraded, with a more robust 80mm travel suspension fork and a powerful 750-lumen high-beam headlight. A notable feature is the “Spanning Halo+” rear light. It’s not just a light with turn signals; it has an integrated radar system that detects vehicles approaching from behind. It alerts you on your display, showing you how close the vehicle is and even how fast it’s traveling, adding a layer of situational awareness.
Who is it for? The Max is for the enthusiast or the serious commuter. If you want to get where you’re going faster, need the extra power and payload for heavy-duty tasks, and value features like the rear radar system, the Max provides a different level of experience.
The Rad Power Bikes Buying Experience
Rad Power Bikes pioneered the direct-to-consumer ebike model but has since evolved. They now operate as an omnichannel brand. You can order your bike online and have it shipped to your door. However, the company is also expanding its network of physical Rad stores and local bike shop partners. This gives you the chance to see a bike in person, take a test ride, and have a local resource for support.
If you buy online, expect to do some light assembly. The bike arrives mostly built, but you’ll need to attach the handlebars, front wheel, and pedals. Rad provides a quick-start guide and the necessary tools to get the job done. For community support, the Rad Owners Forum is an excellent resource.
Pros and Cons of the RadRunner Plus (2025)
After extensive testing, here are our thoughts on the highs and lows.
The Verdict: Is the RadRunner Plus the Best of the Bunch?
So, is the RadRunner Plus proven to be the best RadRunner? The answer depends entirely on the rider. For pure simplicity and value, the base RadRunner wins. For ultimate speed and technology, the RadRunner Max is the clear champion.
So where does that leave the Plus? It carves out its place as the best all-around value in the lineup. It’s the definitive choice for the rider who wants a do-it-all utility bike that’s ready for passengers and hills right out of the box, without needing to buy a single accessory. It successfully bundles the most impactful upgrades—gears, suspension, and the passenger kit—into one package. This offers a significant step up from the base model for a reasonable price. While it has its trade-offs, the RadRunner Plus is the ideal pick for families and riders looking for the most versatile and user-friendly option.
