Controller Failure Repair in New Orleans, LA
The bike's brain is failing: burning smell, total dead bike with a good battery, or erratic surging assist.
New Orleans riders deal with heavy humidity, and one documented cause of this symptom is water intrusion. It is worth ruling out first here, though it is one cause among several and not a diagnosis on its own.
New Orleans is made for e-bikes in one way and hard on them in every other. The city is pancake-flat, the grid is compact, and the Lafitte Greenway now links the French Quarter area to Mid-City and Bayou St. John, while the levee-top Mississippi River Trail runs upriver for miles. But this is one of the wettest, most humid big cities in America, and moisture is merciless on connectors, bearings, and battery contacts. The bigger issue is the streets themselves: New Orleans potholes and buckled pavement hammer wheels, spokes, racks, and headsets harder than anywhere else we service. Frequent wheel truing, torque checks, and corrosion inspections are simply part of owning an e-bike here.

- Heat stress from sustained loads
- Water intrusion
- Blown MOSFETs
- Connector corrosion
- Overloading from aftermarket modifications
How it gets fixed

What a mechanic actually checks first
The controller is where this diagnosis ends, not where it starts. Confirming a dead controller means clearing everything around it first, in order. The battery gets measured at its output contacts, and if the bike will power up at all, checked under load, because a controller cannot be judged on a starved power supply. The main fuse gets pulled and inspected, along with every connector between battery and controller, since a dead bike with a good battery is more often a fuse or a corroded connection than a cooked board.
Only then does the controller bay get opened: a visual inspection for heat discoloration, melted insulation on the phase wires, swollen components, and the smell, because cooked electronics announce themselves. After that come the signal checks: throttle and pedal-assist inputs measured at the controller plugs, and the motor's hall sensors tested through the controller connector. That last step matters, because it separates a controller that has actually failed from one that is being fed bad signals and only looks guilty.
If the controller is condemned, the second half of the job is matching. Voltage, current rating, connector standard, and sensor type all have to agree with the rest of the bike, and on brands with proprietary plugs the options narrow to an OEM unit or a harness-level conversion, which changes the quote.
Try this before you call
A controller that smells burnt or a bike that is fully dead with a confirmed-good battery points here. There is no DIY fix for a blown controller, but confirm the diagnosis before buying parts, since dead-bike symptoms are more often a fuse or connector. Controllers must match your bike's voltage and plug standard; a tech will spec the right unit.
Brand notes for this symptom
These apply to the brand nationally, not to New Orleans specifically.
- Rad Power Bikes$140 to $260
Controller faults are the signature Rad failure, especially on 2019-2022 RadRunner and RadRover builds. Symptoms are a dead bike with a good battery or assist that surges then quits. Replacement controllers are plentiful and the swap is routine.

Louisiana e-bike rules
Louisiana follows the three-class e-bike model: Class 1 pedal-assist up to 20 mph, Class 2 throttle-assist up to 20 mph, and Class 3 pedal-assist up to 28 mph. E-bikes are treated like bicycles under state law, so no driver's license, registration, or insurance is required. Louisiana's bicycle helmet statute requires riders under 12 to wear a helmet, and that rule extends to e-bikes. E-bikes may generally use bike lanes and paths open to bicycles, though local governments and levee authorities can set their own restrictions.
