We repair Rad Power Bikes e-bikes at every Wilson's shop, wherever you bought yours and however old it is: flat tire repairs from $40, hydraulic brake bleeds from $15, brake repairs from $25 and error code fixes from $35, parts and labor included. A simple inspection, where we look it over and tell you what we find, is always free, and express service runs at every shop. We don't sell Rad; we service it, the same as every other brand.
That matters more for Rad owners than for most. Rad Power Bikes, Inc. filed for Chapter 11 bankruptcy on December 15, 2025, and the brand now belongs to a new owner, which says it has no obligation to provide warranty or service for Rad e-bikes bought before that date. Below are the repair prices, the hardware on each current model, what our technicians check for each fault, and what the warranty situation is.

Which Rad Power Bikes models do we repair?
All of them, current and discontinued. The current line, from Rad's own spec sheets, runs entirely on hub motors and hydraulic disc brakes; the tires and gearing are where the models differ, and they decide which parts a repair needs:
| Rad model | Type | Motor | Brakes | Tires | Gears |
|---|---|---|---|---|---|
| RadRunner | Cargo utility | 750W rear hub | Hydraulic disc, 180 mm rotors | 20 x 3.3 in | Single speed |
| RadRunner Plus | Cargo utility | 750W rear hub | Hydraulic disc, 180 mm rotors | 20 x 3.3 in | 7-speed |
| RadRunner Max | Cargo utility | 750W rear hub | Hydraulic disc, 180 mm rotors | 20 x 3.5 in | 8-speed |
| RadWagon 5 | Long cargo | 750W geared hub | Hydraulic disc, 180 mm rotors | 20 x 3.3 in | 7-speed Shimano |
| RadWagon (2026) | Long cargo | 750W rear hub | Two-piston hydraulic disc, 180 mm rotors | 22 x 3 in | 7-speed Shimano |
| Radster Road | Commuter | 750W geared hub | Hydraulic disc, 180 mm rotors | 29 x 2.2 in | 8-speed Shimano |
| Radster Trail | Off-road | 750W geared hub | Hydraulic disc, 180 mm rotors | 27.5 x 3.0 in | 8-speed Shimano |
| RadExpand 5 Plus | Folding | 750W geared hub | Hydraulic disc, 180 mm rotors | 20 x 4.0 in | 7-speed Shimano |
From Rad Power Bikes' product pages, read November 2026. Older models such as the RadCity, RadRover, RadMini, RadWagon 4 and earlier RadRunners are serviced the same way; their brakes and gearing can differ, so we check what yours has.
What we check, fault by fault
Rad e-bike won't turn on or won't charge
We start with the charger and the charging port, then the battery's connection to the e-bike, its key or passcode lock and the pack's voltage, then the controller and wiring. A won't-turn-on repair starts at $35, a charging port at $35, a charger at $35, and a battery load test and health report at $50. If the battery is the fault, battery repair (BMS from $200) or replacement is quoted after the test. See won't turn on or won't charge and e-bike battery replacement.
An error code on the display
A Rad display shows a code when the controller detects a fault: a sensor, the throttle, the motor wiring, the brake cutoffs or the battery. We read the code, then test the part it points to. Fixing the fault behind a code starts at $35; looking it over is free.
Brakes that feel soft, squeal or rub
A loaded cargo e-bike asks a lot of its brakes. When a hydraulic lever feels spongy or pulls to the bar, we check for air or a leak in the line and bleed the system (from $15); when a brake squeals or rubs, we check pad wear, rotor straightness and caliper alignment (pads, disc clean and clearance from $25, rotor from $35). If your Rad has cable-operated brakes, a cable and lever job starts at $75. See brake repair.
Flats on fat and cargo tires
Rad's 20-inch fat tires carry a passenger, a child seat or a full rack, and on a rear hub motor the back wheel holds the motor, so a flat takes more work than on a pedal bicycle. An inner tube flat starts at $40, a new tire and tube at $65 to $120, and an airless tire install at $40. See tire repair.
Chain, gears and wheels under load
Weight and motor power wear a chain, cassette and wheel bearings faster than leg power alone. Chain and drivetrain replacement starts at $45, derailleur alignment at $40, and wheel truing and spokes at $100. The RadRunner is single speed, so there is no derailleur to adjust; we check the chain, freewheel and chainring instead. See e-bike chain and drivetrain repair.
Pedal assist cutting in and out
The pedal assist sensor, the speed sensor and its magnet, and the brake cutoff switches all tell the motor when to help. We test each one; sensor repairs start at $35.
Hub motor noise or no motor power
Every current Rad drives through a hub motor. We check the phase wires, hall sensors and connectors first, then the motor itself. Motor repair starts at $100. See motor repair.
Folding hinge play on a RadExpand or RadMini
If the frame hinge or the folding stem has play, or the latch won't close tight, stop riding it and bring it in: folding hinge and latch repair starts at $30.
Never charge a battery that is wet, swollen, damaged or has been in a crash: bring it straight in. A swollen or wet battery safety check starts at $70.
What happened to the Rad Power Bikes warranty?
Rad's own warranty page splits owners by purchase date:
| When you bought it | What Rad's warranty page says |
|---|---|
| Before December 15, 2025 | Rad Power Bikes, Inc. (now New Summit Collective, Inc.) filed for Chapter 11 on December 15, 2025, and the brand has been under new ownership since February 27, 2026. Warranty claims on these e-bikes go through the bankruptcy court's Proof of Claim process (case 25-02183). The new owner, Rad Life Mobility, says it has no obligation to provide warranty or other service for them, and that it is reviewing upgrade policies it may offer at its discretion. |
| After May 15, 2026, new from Rad or an authorized Rad retail partner | 2 years on the frame, fork, stem, handlebar, headset, seat post, brakes, lights, bottom bracket, rims and wheel hub; battery 2 years or 300 recharge cycles; 1 year on pedals, freewheel, crankset, cassette, derailleur, shifter and saddle. Parts not listed aren't covered. |
| In between | Ask Rad's customer service which terms apply. |
Under the current terms, wear items aren't covered (brake pads, chains, chainrings, cables, hydraulic brake hose and fluid, tires, tubes, bearings and spokes), and neither is water damage, rust, an accident, or damage from unauthorized service or parts. Modifying any electrical component voids the warranty. Labor is covered only when Rad approves it before the work, and claims start in Rad's Help Center with photos or video.
Summarized from Rad Power Bikes' published Limited Warranty Terms (last updated May 14, 2026), read November 2026; Rad's own terms decide every claim. General information, not legal advice.
So if you bought a new Rad after May 15, 2026 and the fault could be a defect, start with Rad. For an older Rad, for wear items, or for crash and water damage, bring it to any Wilson's shop. A simple inspection is free, and we tell you what we find before any work starts.
Is an old Rad e-bike worth repairing?
Usually, yes. A current Rad is built on an aluminum frame, a hub motor, a removable battery and standard bicycle parts, and most faults are in parts that wear or plug in: tires, brake pads, chains, chargers, sensors and controllers. Most of those repairs start between $15 and $55. The bigger questions are the battery and the motor, and we answer those with a test before you pay for anything: the full diagnosis is $30, waived if you go ahead with a repair over $100. If the repair would cost more than the e-bike is worth to you, we tell you.
