1, Can I order some samples at first to test the quality?

Of course. We accept the sample orders. We can do OEM, so the configurations can be adjustable if you have any request.


2, How the e-bikes are packed ? What the user has to assemble when they received the e-bikes?

All of our bikes are adopted the 85% disassembled packing. The bicycle will be packed in 7-layer corrugated carton with all its components inside, in most cases you will need to assemble the front wheel, seat, handlebar and lights if included, this process should not take more than 2 hours no matter the skill level.


3, How far can I go on a single charge?
Mileage depends on each bike model and a number of factors including the weight of the rider, added gear, terrain, tire pressure, temperature, wind speed, etc. The average range on a fully charged battery is between 20 and 30 Miles. If you want to ride a long range, you can choose e-bikes with larger batteries.


4, Are electric bikes safe?

Absolutely! Electric bikes are as safe to ride as a regular bike. When you need to stop or slow down, all you need do is apply the brakes and release the hand throttle or stop pedalling to cut the power. All our Electric Bicycles bikes are built to the highest quality.


5, What maintenance is required?
Aside from keeping your battery charged, maintaining Electric Bike is the same as any bicycle. After the bike's been ridden about 100 miles you'll need a basic tune-up. This is standard procedure for all new bikes as they're broken in. The most important (and simple) thing you can do is check your tire pressure regularly, and keep them inflated as indicated on the tire. If you're riding in wet conditions, you'll want to take extra care and make sure you keep your drivetrain clean and well-lubed.


6, When to Charge the Battery?

We recommend charging the battery back to full after each ride so the battery is topped off and ready to go the full range whenever you want to ride the e-bikes!  

A battery with a partial charge can be left without immediately charging back to full. If a battery is left empty for an extended period, however, it can become damaged and/or non-functional. So we suggest you to charge the battery if you don't use e-bikes exceeding two months.
