In this Spec Review we will take a look at the build, design and components on the Rad Power RadMission ebike.
The RadPower RadMission is a stylish single-speed e-bike designed for city riding and zipping around town. This is a budget-friendly class 2 e-bike at just $999 — making it the least expensive in RadPower’s lineup. The RadMission has a top speed of 20 mph, with both pedal assist and a twist throttle on the handlebars. The frame comes in two sizes, a high-step with a 31-inch standover height, and a mid-step 28-inch standover height. This bike has four levels of assist, a 500 watt high-torque (50Nm) motor and estimated range of 20 – 45 miles. RadMission also reduced the weight on this bike compared with their other e-bikes, so it weighs in under 50 pounds at around 47lb total weight. The sleek frame design and narrow tires will quickly get you to the library, cafe, a friend’s house, and back again while eliminating gas emissions, reducing your carbon footprint and saving your budget!

The RadPower RadMission is a new take on a classic style with narrow, street tread tires, a lighter 48v battery, 500W geared hub motor, and racing style seat and handlebars. The RadMission has clearance under the fork for added fenders (optional) and bosses on the steer tube for an attached basket or rack. It comes in either a mid-step or high-step frame design, with three color choices for each. There are also several frame sizes as well. This bike is a good option for those who want a simple, streamlined bike that looks like a classic single speed with the added benefit of a powered drivetrain that can offer up to 45 miles of range.
The RadMission comes in both a mid-step or high-step frame with three colors each:

Shifter and brake cables extend from the handlebars down to the lower part of the headtube. These are not as integrated as on other e-bikes, probably because the tubing is rather narrow to maintain the classic look — which doesn’t leave a lot of room for integrated cables. The cables connect on the underside of the downtube beneath the battery.
The RadMission uses a 48v, 10.5Ah (504Wh) Lithium battery. This is slightly smaller and lighter than the batteries on their other bikes, but the RadMission is intended to be ridden as more of a recreational, zip around town bike rather than a cargo or commuter bike, so the lighter battery makes sense. You still get good power and adequate range with the 500W hub motor, so the combination provides just enough assist. The battery attaches externally to the downtube like other Rad bikes, and it locks into place so it can’t be stolen — but you can take it into your office during the day to charge. A standard 48v, 2amp charger is included. This will plug into any standard wall outlet.
As with other bikes, there are a few things you can do to protect the battery and extend battery life, including:
- Avoiding charging the battery above 80%
- Avoiding discharging the battery below 20%
- Reduce charge rate
- Store battery at 50% capacity for periods o long inactivity
- Store battery at a moderate temperature
The controller is separate from the battery on the RadMission to keep the battery pack lighter. It is attached on the exterior side of the seat tube so it is tucked out of the way. The controller draws power from the battery to support the motor, lights, and handlebar display.
The RadMission has a geared hub motor that securely tucked inside the back wheel. The 12-magnet cadence sensor on the pedal crank measures your pedal cadence to provide enough assist in each level. The half-twist grip throttle also draws power off the motor to provide assist without pedaling. This drivetrain system can get between 25 – 45+ miles of range depending on assist level and terrain. All wiring is water resistant and there are integrated headlights and taillights for safety.
LED Control Panel
The handlebar display on the RadMission is very simple. 5 green lights on the top of the display show overall battery power and 5 yellow lights indicate your level of assist. There are only four other buttons: a +/- button for adding or decreasing assist level, a light button to turn on or off the integrated lights, and a power button. The display doesn’t show distance traveled or current speed — it is simply a battery and assist display. However, on this bike that’s about all you need and again, the idea here is to reduce weight and reduce cost while maintaining functionality, which RadPower has done on the RadMission bike.
- Walk Mode
- There is a walk mode you can use to help support the weight of the bike if you need to walk it across a crosswalk or up hill. The walk mode is a bit quick, but it’s nice to have this feature on an e-bike since the ~50 pound bike weight can be a bit much to manage manually.
- The Headlight is automatic, but you can turn it off on the control panel if needed.
- The taillight is also integrated and it is brake sensitive, so when you pull the brake levers the brake lights will light up like they do on a car. This increases both safety and visibility when in traffic.
The RadMission is a single gear with one 16T freewheel cassette in the back and a 50T chainring in the front. Since this is a freewheel, you can pedal backwards and forwards which is nice and the double guard chainring holds the rust resistant chain tight and in line. This reduces the likelihood of chain drops and enables a smooth pedal stroke regardless of gear or assist level. However, it can get hard to pedal when headed uphill or at times when you have maxed out assist and you’re missing the option of more gears. For riders who prefer a high-cadence, low-torque riding pattern, the RadMission can feel a bit heavy and sluggish due to the single gear system. But the assist provides enough support to offset the single gear most of the time. You only notice it on hills or when nearing the bike’s weight capacity.
Tektro Aries caliper brakes with 180mm rotors on both front and rear provide enough stopping power. The brakes don’t feel soft and you have adequate and responsive stoppage when needed. The levers are aluminum alloy comfort grips with a rubber surface and ball stopper to prevent your hand from slipping off. The brake levers have a motor cutoff switch so as soon as you tap the brakes the motor shuts off power — this way you’re not wearing down your brakes while the motor is engaged. It also naturally slows the bike without having to apply too much friction to the rotors.
There is no suspension front or rear. You can buy an optional Suntour suspension seat post from RadPower if desired. The front fork is steel for stability but it doesn’t offer any suspension. Tires are 2” wide which is wider than a road tire so you do have a bit more comfort than on a classic road bike. But these are not the typical wide, burly tires found on other Rad bikes. You do get a nice bit of tread to help roll over dirt, grass or gravel. We don’t recommend taking the RadMission off road, but the tires do help offset a bit of the hardtail design.
RadPower has added the Wellgo composite platform pedals to the RadMission. Again, they are lightweight but may break if you drop your bike on one side all the time and hit the pedal. Reflectors on the edges of the pedal add to your visibility in traffic.
Grips and Saddle
The RadMission has simple rubberized round grips that are easy to hold with just a bit of texture. They are fine for casual riding and just the right width around.
The saddle is a little more narrow than we would expect on a commuter / city bike. This is a basic saddle that is narrow and minimally padded. Friction points are reduced on this type of saddle, but it isn’t overly cushioned and may feel uncomfortable to new riders. You can always add a gel seat cover or upgrade to a more comfortable saddle if needed.
Wheels and Tires
Unlike RadPower’s other bikes, which are usually wide with heavy tread for varied riding conditions; the RadMission has narrower 2” (1.95”) wide and 27.5” high tires. But they still have a good amount of tread on them, so they’re not slick, even on city sidewalks or cement walkways. These are puncture resistant, feature a reflective sidewall and use standard tubes for convenience. Rims are double-wall aluminum, 36 hole and the spokes are a 12-gauge stainless steel in black. In general, the wheels and tires make the bike feel very sturdy while the narrow width provides more navigation and easier handling on tight corners and around pedestrians.
RadPower Bikes offers a ton of accessories from gear to bags, clothing, helmets and tools. You can also add racks, mirrors or other accessories to your bike. RadPower also offers replacement parts for bike components such as batteries, chargers, fenders, and lights.
In summary, the RadMission is a fun and very affordable e-bike. The two frame choices (mid-step and high-step) make it a good option for different size users — and those with limited mobility or knee issues can opt for the mid-step without missing functionality or frame strength. There are also two frame sizes in both the high-step or mid-step and three colors each — a selection that is hard to find at this price point. Rad has been an industry leader in direct to consumer e-bikes and the RadMission provides some of their more popular features on an affordable bike. This is a good option for anyone looking to make their first venture into the electric bike world with a zippy bike that is classically styled and easy to handle.
