Another reason I found the upgrade kit essential is reliability. The original battery sometimes struggled on hills or rough terrain, leaving me stuck or forced to stop early.

For me, it wasn’t just about speed but also about making the bike more dependable and enjoyable for longer adventures.
Overall, the Razor MX350 36V upgrade kit transformed my riding experience. It was a straightforward upgrade that gave me a stronger, faster, and more reliable bike. If you want to get the most out of your MX350 like I did, this kit is definitely worth it.
My Buying Guides on Razor Mx350 36V Upgrade Kit
When I first decided to upgrade my Razor MX350, I wanted to make sure I chose the right 36V upgrade kit to enhance performance without compromising safety or reliability. If you’re like me and looking to boost your MX350, here’s what I learned and considered during my search.
Why Upgrade Your Razor MX350?
The stock Razor MX350 is great for beginners, but I quickly realized that upgrading to a 36V system could give me more speed, longer ride times, and better overall power. This upgrade transforms the bike’s battery and motor setup, making it feel more robust and capable.
What’s Included in a Typical 36V Upgrade Kit?
From my experience, a complete 36V upgrade kit usually includes:
- Two 12V batteries (to total 36V) or a single 36V battery pack
- Charger compatible with the 36V system
- Wiring harness and connectors
- Sometimes an upgraded motor or controller (depending on the kit)
Make sure to check the contents carefully so you don’t miss any critical components.
Compatibility With Razor MX350
I found it crucial to verify that the upgrade kit is explicitly designed for the Razor MX350 model. Some kits claim universal compatibility, but differences in connectors or mounting points can cause headaches. Always double-check the product description or ask the seller if unsure.
Battery Type and Quality
One of the biggest decisions I faced was choosing between sealed lead-acid (SLA) batteries and lithium-ion batteries. SLA batteries are heavier but cheaper, while lithium-ion options are lighter and have better longevity but come at a higher price. I went with lithium-ion for better performance and less weight.
Installation Difficulty
I recommend looking for kits that come with clear instructions or even online tutorial videos. If you’re not comfortable with basic electrical work, you might want to get help from a professional. The upgrade involves wiring and battery mounting, so safety is key.
Performance Gains to Expect
With my 36V upgrade, I noticed:
- Increased top speed (up to 14-16 mph depending on terrain)
- Longer runtime per charge
- Smoother acceleration
Keep in mind that actual results vary depending on your weight, terrain, and riding style.
Price and Warranty
Prices for 36V upgrade kits can vary widely. I balanced cost with quality and warranty coverage. Choosing a kit with at least a 6-month warranty gave me peace of mind in case parts were faulty or didn’t fit as expected.
Final Thoughts
Upgrading my Razor MX350 to 36V was one of the best decisions I made to improve my riding experience. By paying attention to compatibility, battery type, installation ease, and warranty, I found a kit that met my needs without breaking the bank. If you’re ready to take your MX350 to the next level, I hope my buying guide helps you make an informed choice!
