~ Why the Juggernaut Ultra FS is 🔥 ~

Integrated front light
Never ride blind again. Our bikes come with front lights integrated with the main battery of the bike
Fast charging
Our batteries charge up to 80% in just 2 hours. This means less time charging and more time riding!
Fast and Fun
Reach speeds up to 28mph (speed limited) and 36mph (off-road). More speed and more fun!
Removable battery
All our bikes have removable batteries. Each bike comes with a unique key that's necessary to unlock battery.
Mid-drive motor
Mid-drive motors are much more efficient than hub drives as they can use the bike's gears as transmission. Climb the steepest hills. Conquer anything. 
Future-proof powertrain
Our motors and batteries are built using an open platform design. This makes upgrading the motor and battery plug-and-play.
Leading Warranty
Limited lifetime warranty on our frames + 1 year warranty on all electronics.
Note that wear and tear is not covered under warranty.

A really fun to ride eBike.

Been taking a few rides to get acquainted. Very smooth on the road and gets even more fun as you get into the off road trails. The motor is strong and the upgraded Wren suspension a pleasure. The 21 ah battery is a definite plus. Overall, decently built and a fun toy. The Upzy team was a great help in getting the order facilitated with Biktrx.

Please inspect the packaging of your item(s) when they arrive. If the packaging appears heavily damaged on the outside, you have the opportunity to reject the shipment. We encourage you to gather photo evidence at this point too. Once the shipment is delivered or you sign and accept the shipment, we no longer have the authority to file a claim with the shipping carrier and anything thereafter will be treated as a return. In the rare instance the item inside is damaged, kindly do not worry as we will work with you to resolve the situation. You can provide any photo evidence to aftersales@upzy.com.

Please note we pack all our products as best as possible. Sometimes the packaging may get dented in shipping, but do not be concerned as the inside contents are usually still intact.



For any warranty/aftersales issues with your item(s), you can contact us at aftersales@upzy.com.  You may contact the manufacturer/distributor, but Upzy.com must also be informed of any issues.  Upzy.com will try our best to resolve any issues in accordance with our and the manufacturer’s/distributor's policies, however we cannot guarantee that it will always be to the customer's satisfaction.  It is the customer's responsibility to work with Upzy.com to resolve any warranty/aftersales issues.

Some items in our store require assembly and potentially some adjustments/modifications/minor fixes to allow it to function to the customer's satisfaction, professional assembly/expertise might be required (depending on the customer’s experience and abilities).  Please note that Upzy does not pay or reimburse for any labor or service costs if the item is taken to a professional.

In addition, if customer decides to adjust/modify/fix the item themselves using parts they purchased themselves, Upzy does not pay or reimburse for the parts or labor incurred. 

Ultimately, customer bears sole responsibility for any charges or changes to the product using outsourced labor and non-warranty parts.



If you are not completely satisfied with your purchase, please email us at aftersales@upzy.com. We can arrange a return authorization within 15 days of the receipt of your product.

We work very hard to ensure that we offer the absolute lowest prices online.  We want you to feel confident that you are getting the lowest price for your product compared to any other online store, and we will match their lowest price accordingly.


Our 100% Price Guarantee has some limitations:

  • It does not apply to prices for our own store bought at different dates.  We reserve the right to change prices due to fluctuating sale prices from our manufacturers.  Once purchased, you "lock" in that sale price.  If price for that same item in our store decreases tomorrow or at any future date, you will still be locked into your original sale price.
  • Promotions such as rebates and buy one, get one free offers are not eligible
  • The item must be in stock on the competitor website
  • The competitor must be an online store (it cannot be a physical retail store) and it cannot be the manufacturer's own online store
  • The website cannot be a discounter or auction website (eg eBay, Overstock, etc)
  • The competitor must be an Authorized Dealer for the product in question.  The product has to be genuine and cannot be a knock-off sold at a much lower price.
  • The Price Match Guarantee is for the final price after shipping and sales taxes.  A lot of online stores advertise a lower price but tack on shipping charges and sales taxes in the checkout process, ultimately making their price higher than ours.  We never have hidden fees. 
  • If you purchase something from us and subsequently ask for a price match from another store, it has to be done within 5 days after purchase date.

Feel safe knowing that you are purchasing the best possible price online from Upzy - Buy from us today!
