SurgeGlide Premium E-Bike Parts & Upgrades

About Us

At surgeglide, we believe that everyone should have access to the incredible experience of riding an electric bike. That's why we're dedicated to providing the highest quality electric bike conversion kits on the market, making it easy and affordable for you to transform your beloved bike into an e-bike.

Frequently asked questions

Do I need to cut any wires or perform soldering? How difficult is the installation

Absolutely not. All our upgrade kits use factory-matching plug-and-play connectors. We use high-quality heavy-duty wiring and correct wire sequencing designed specifically for your bike's original wire harness. Installation typically takes 15-30 minutes

What is the return policy?

Our goal is for every customer to be totally satisfied with their purchase. If this isn't the case, let us know and we'll do our best to work with you to make it right.

Are any purchases final sale?

We are unable to accept returns on certain items. These will be carefully marked before purchase.

How can I be 100% sure this controller/motor fits my Rad Power Bike model?

Compatibility is our top priority. We have created a Guaranteed Fit Guide within each product description. The model list (e.g., RadRover 6 Plus, RadRover 5, etc.) specifies which bikes are plug-and-play. please use our Live Chat and send us a photo of your stock controller for instant confirmation

Will replacing my factory controller solve the power loss or shutting-off issue when climbing hills?

Yes! The stock Rad controller often triggers thermal protection (overheating) or over-current protection on steep hills, especially under heavy payloads. Our new-generation 35A high-output controller increases peak power and torque for effortless hill climbing, eliminating sudden thermal cut-offs while keeping operating temperatures low.

When will I get my order?

We will work quickly to ship your order as soon as possible. Once your order has shipped, you will receive an email with further information. Delivery times vary depending on your location.

Are your replacement/compatible batteries safe? How do you ensure quality control?

Safety is our top priority. Unlike unverified Marketplace batteries, all our replacement battery packs adhere to strict Tier-1 OEM procurement protocols:
​100% full cell traceability back to Tier-1 cell manufacturers (e.g., LG, Samsung).
​Rigorous lab testing reports provided, including aging tests, shock/vibration tests, and high-temperature thermal runaway safety tests.
