Euy e-Bikes FAQs, we're here to help answer your questions. Answers to e-bike shipping, assembly and other frequently asked questions.

Shipping & Delivery

We generally ship your ebike by FEDEX, from City of Industry and Rancho Cucamonga in California.

Currently, we only provide FREE shipping to the lower 48 states in the US(except Hawaii, Alaska, and Puerto Rico). And we DO NOT ship to PO BOXES or APO.

(If you want to ship to other countries, you can contact customer service.)

It normally takes 2-8 working days, depending on your location. Please note that this is not guaranteed and delivery time may be extended due to covid-19. A shipping confirmation email will be sent to your email once the order has shipped.

U.S. orders will be dispatched from U.S. warehouses, and the carrier is FedEx, and it will take about 2 to 8 working days.
All countries except the United States are shipped from Chinese factories and shipped by ship, and the shipping time is about 60 days.
We are unable to provide any additional shipping information or documentation for any third party shipping. Any delivery dates provided by EUY are estimates.

After shipping,Change of Address: If you successfully change your address, $20 will be charged as a processing fee. If you fail to change your address, you may refuse the package and 10% of the ebike cost will be charged as a reshipping fee.

Throttle & Pedal Assist

Yes, you can --that is what it is there for! However, using the throttle the entire time you are riding will impact how long the battery will last, getting you 20-40 miles on a full charge. (The specific mileage depends on the model)

Battery & Charging

Up to 60 miles, more or less depending your riding style, level of pedal assist an/or throttle, rider weight, hills, and headwinds/tailwinds.

Charging the battery from empty to full typically takes 5-6 hours. In rare cases, it may take longer to allow the battery management system to balance the battery, particularly when the bike is new or after long periods of storage.

Check whether the indicator light of the charger is displayed normally, test whether the output voltage of the charger is greater than 48V, and troubleshoot the charger first.

If there is no problem with the charger, it is likely that the fuse of the battery charging port is damaged. You can try to go to a local repair shop to replace the fuse.

If you still can't solve it after replacement, please provide a video showing that the battery cannot be charged, provide order number, and contact after-sales, the email is service@euybike.com.

Like any other device that uses a lithium-ion battery, the range and performance of your e-bike can be dramatically affected by temperature changes. Have you noticed that your iPhone or Android battery life goes down while skiing or hiking on cold days, but returns to normal when you go back inside? Temperature plays a big role in the effectiveness of the battery.

Since e-bikes can be ridden in very hot, and very cold temps, it's important to keep your battery in mind when riding in extreme conditions. Here are some tips to preserve the life and performance of your battery:

Charge and store your battery in a cool, dry space, away from high humidity. This may mean removing the battery from your bike for charging.

If you won't ride your bike for a while, charge the battery first, and then store it at a 75% - 80% charge level.

Store and charge your battery in a dry location. Water, humidity, and damp conditions are not good for any electrical device.

Inspect and maintain the electrical contacts between the battery and the controller (the connection where you plug the battery into the bike) on a regular basis. Make sure the prongs aren't bent. If the interface becomes contaminated with grit, mud, or snow, clean it before connecting your battery.

Don't leave your bike in the trunk of a hot car (think Phoenix in July) with the battery attached. Remove the battery and take it with you instead.

When you ride your e-bike in cold temperatures, the range will be reduced. If you park outside overnight, bring the battery back outside only when you are ready to ride to minimize the impact of temperature on range.

It's fine to ride most e-bikes in the rain. You should dry the contacts on the battery to prevent corrosion and oxidizing. Electrical contact cleaner can be used to keep that connection clean if needed. In extreme weather (for example, in a community where roads are salted in winter) you can apply battery terminal grease as a preventative.

If you can't remember the specifics, keep in mind this rule of thumb: "if it's too hot or too cold for YOU, it's also too hot or too cold for your battery." Your battery is comfortable at the same temperatures you are!

With these tips in mind, your e-bike and battery will live a long, healthy life. Happy riding!

Yes, you can --that is what it is there for! However, using the throttle the entire time you are riding will impact how long the battery will last.

The max range depends more or less on the model configuration and your riding style, pedal assist and/or throttle level, rider weight, slope and headwind/downwind. See the product information overview of the model for details.

Cleaning your Euy electric bicycle is just like cleaning a normal bicycle. It is recommended to remove the battery and rinse it with water. After rinsing, wipe it with a dry cloth and apply a little oil to the key parts.
