When an Aventon bike cuts out, will not power up or shows a fault that points past the display, a new controller is the part owners end up searching for. Aventon sells one as a replacement, in a long list of model-specific options. This guide covers what that page lists, what it leaves out, and what to rule out before you spend about $84. We read a copy of the page archived on November 30, 2025, because the live page would not load when we checked on October 28, 2026, so confirm the options and the price on Aventon's current page.
What Aventon's controller page says
The page calls the part the Aventon Controller with Throttle on Demand (TOD), "designed as an OEM replacement part," and says it "can impact several critical components, including the motor, terminal, lights, PAS sensor, and wire harness." Each controller is "tailored to fit specific Aventon bike models," and you pick yours from a dropdown. The archived copy listed 19 options, all at $83.99:
- Abound: Abound SR / Abound LR (one option).
- Aventure: Aventure, Aventure 2 - with Terminal, and Aventure 3.
- Level: Level 2 and Level 3.
- Pace: Pace 350 ToD, Pace 350.2, Pace 350.3, Pace 500 / Level ToD, Pace 500.2, Pace 500.3 and Pace 4.
- Sinch: Sinch ToD, Sinch ST, and Sinch 2 / Sinch 2.5 (one option).
- Soltera: Soltera SS, Soltera 7S, and Soltera 2 / Soltera 2.5 (one option).
Where owners could order the wrong one
Pace 350 ToD, Pace 350.2 and Pace 350.3 are three separate options, as are Pace 500.2 and Pace 500.3, and Level 2 and Level 3. The only option that names a plain "Level" is the combined "Pace 500 / Level ToD", and the page explains neither that option nor what "with Terminal" means on the Aventure 2. Ask Aventon if either matches your bike.
Note what is missing too. Aventon's display pages, which we covered in our guide to replacing an Aventon display, name the Level 4, Pace 5, Soltera 3 ADV and Ramblas, but the archived controller page has no option for any of them. We do not know why, and we are not suggesting that a controller listed for another model fits. If your model is not listed, ask Aventon before you buy.
Before you decide it is the controller
A fault that looks like a failed controller can start somewhere simpler. These steps are our general advice, not Aventon instructions.
- Check the basics. The battery should be charged and seated firmly, and the charger should behave normally.
- Look at the plugs. With the bike off and the battery removed, reseat the display, motor and throttle connectors and look for bent pins, corrosion or water. Never force a plug that does not seat easily.
- Read the code. Our guide to Aventon error codes explains the three systems behind them. A code points to an area of the bike, not always the controller. If the trouble is the throttle, see our Pace 500 throttle guide.
- Note the symptom. Does the bike never power up, cut out under load, or misbehave in only one assist mode?
- Ask Aventon to confirm. Give them your exact model and any code before you order.
Our e-bike repair online page walks through a three-minute diagnosis, and our e-bike electrics 101 guide shows how the motor, controller, display and sensors fit together.
Ordering, and what the page does not say
Get your exact model name, including any ".2" or ".3" suffix, from your owner's manual or receipt. Photograph the old controller and its plugs before you disconnect anything, and keep the old unit until the new one is tested.
The text we read does not explain removal or installation. It does not say whether a replacement needs set-up, pairing or a software step, or whether it must match your display, and it never mentions generic controllers. On many e-bikes the controller, display and motor exchange data, so a plug that fits does not prove a part works. This guide therefore claims no generic controller fits an Aventon, and it publishes no pin charts or wiring details.
Where RideRow fits
As of October 28, 2026, RideRow does not list any Aventon controller, and nothing in this guide says a RideRow part replaces one. If your repair involves connectors, throttles, sensors or wiring, you can browse our e-bike spare parts.
