Updated December 2025
Rad Power bikes have made a name for themselves creating rugged, performance oriented e-bikes that are intended to be used for taking trips that would otherwise have to be done in a car or SUV. Their design allows them to go off road, haul all sorts of loads, and even bring the kids along.
Rad Power has expanded over the years and now has a wide range of bike styles in their lineup. On these bikes are either one of two brake types - a cable actuated disc brake or a hydraulic disc brake. Most of their recent models use a hydraulic disc brake and are either unbranded or from the brands Tektro or Gemma. On older models it was more common to find a cable actuated disc brake.
Quick Tip: Rad Power seems to have moved most, if not all, of their current models to brakes that use a Shimano B-type pad. You can find replacements, in multiple compounds, here: Rad Power Replacement Brake Pads

Previous Rad Power Brake Calipers
On older Rad Power bikes there were additional pad types used and this depended on if the brakes were hydraulically or mechanically actuated. Some used the Shimano B-type pad linked above, while others used the same brake pad as a SRAM Level or Avid Elixir brake caliper. For pre-2025 Rad Power bikes it is best to use the photos below to see which type matches the brakes you have.
Rad Power Cable Actuated Brake Pads
The following Rad Power bikes used disc brakes that were cable actuated:
- RadTrike
- RadRunner 2
- RadRunner Plus
- RadExpand 5
- RadWagon 4
For Rad Power bikes that used cable disc brakes the brake models were often listed as either Tektro Aries or Tektro Novela. The brake calipers themselves will be labeled with the model, but you can also use the shape of the pad as an identifier.
On the pivot arm of the caliper you can see the Tektro branding
The Aries brake caliper will have a rectangular shaped pad and was a type used on some Rad Power models from 2018 forward. The Tektro part number for these pads is E10.11 and that correlates with a pad made with an organic compound.
You don’t have to limit yourself to a single compound though. We offer replacement brake pads for these calipers in organic, semi-metallic, or sintered (fully metallic) compounds: Replacement Brake Pads for Rad Power Cable Brakes
The Novela caliper will have a circular shaped pad and was used on models prior to 2018.
Rad Power Hydraulic Disc Brake Pads
The following Rad Power bikes used hydraulic disc brakes:
- RadRover 6 Plus High Step
- RadRover 6 Plus Step Thru
- RadCity 5 Plus High Step
- RadCity 5 Plus Step Thru
When these models were still listed on the Rad Power site their brakes were shown as having a ‘Rad Power approved hydraulic brake caliper.’ There were no discernible markings on the caliper itself, however these calipers used the same brake pads as SRAM Level or Avid Elixir brake calipers.
The hydraulic calipers have no markings on their exterior
To confirm if this is the case with your brakes, compare your pads to the photo below. If your pads match this style, our SRAM Level pads are a direct replacement and you can choose from semi-metallic or sintered (fully metallic) compounds.
