FAQ'S

minus plus
When will the TrailRush ship out? minus plus

In-stock TrailRush electric bikes require extra processing time and will ship out within 1 business days of placing your order. The TrailRush is shipped via FedEx to preserve quality and reduce shipping related issues.

After your order has processed and left our warehouse, please expect approximately 5-10 business days for additional transit time and delivery. Delivery appointment is required and delivery times are dependent on availability by local distribution centers.

Are the bikes water-proof? minus plus

The bikes are not water-proof, they are water-resistant with a rating of IPX4. While we do not recommend leaving the bikes out in the rain or riding in the rain or other hazardous conditions due to personal safety, the bikes can handle low pressure exposure to water. Do not submerge in water or expose to pressurized air or water. Storing your ebike in the elements could shorten the lifespan of the electric bike.

Can I test ride a bike? minus plus

We are a direct-to-consumer eBikes company both in pricing and strategy. Riders will generally pay a premium for the ability to test-ride eBikes through a dealer. However, our bikes have been thoroughly tested by top reviewers such as Electric Bike Review, Electric Bike Report, Cycling Weekly, Clean Technica, Electrek, and many others who have published their reviews on YouTube.

Can I upgrade the battery? minus plus

Unfortunately, this electric bike frame’s 14ah battery pack is the largest available. If you would like extra range, you can purchase a second battery pack here.

Can I switch the handlebars to another model? minus plus

No. The variations you see on the site are the only options we have for our ebikes.

Can you ship to _______? minus plus

We only ship within the US and Canada. The contiguous United States is FREE. Shipping to Canada is $400. Currently, not shipping to Hawaii. We are not responsible for any additional tariffs charged by your local government which is often applied after importing. Unfortunately, we are not able to ship our eBikes directly to Europe or Alaska at this time. You can use a shipping forwarder like ShopUsa.com to reach your country.

What Does Mid-Drive Mean on an E-Bike? minus plus

A mid-drive electric bike means that the motor of the electric bike is mounted in the center of the frame near the bottom bracket, providing power to the crank. This is in contrast to hub motor designs, where the electric motor is in the front or back wheel.

The mid-drive system provides more efficient power transfer, allowing the rider to use the gears of the electric bike for a more natural riding experience and electric motor performance. The position of the motor also allows for a more stable ride as the weight is distributed closer to the center of gravity, as well as more responsive handling with greater torque and hill-climbing ability.

How Fast Can a Mid-Drive E-Bike Go? minus plus

The speed of a mid-drive electric bike is dependent on several factors, such as the power output of the motor and battery capacity. Generally speaking, Class 1 and Class 2 eBikes stop assisting the rider at twenty MPH, while Class 3 eBikes, like the TrailRush, will provide assistance up to twenty-eight MPH. This eBike system has incredible performance for all riders.

Are Mid-Drive Electric Bikes More Efficient? minus plus

Yes, mid-drive eBikes are more efficient than hub motor designs. This is mainly because the electric motor is able to use the bike’s gears and the power is transferred directly to the crank instead of the wheels. This means that you can get more out of each full charge with this electric bike. Keep in mind that although mid-drive motors use the bike’s gears, this doesn’t mean you can’t ride your e-bike if the battery runs out. You just won’t have the extra power that the electric motor provides. EBikes can still be ridden without the electric motor just like you would ride a traditional bike.

How Long Do Mid-Drive E-Bike Motors Last? minus plus

The lifespan and performance of a mid-drive electric bike motor depend on the components’ quality and how it is used. Generally, you can expect your electric bike motor to last anywhere between three and ten years; just make sure to keep up with regular maintenance and follow the manufacturer’s guidelines.
This includes keeping your electric motor dry, as mid-drive motors tend to rust faster than their hub drive counterparts. Protecting and taking care of your eBikes will improve their lifespan and maintain their performance.

Is a Mid-Drive E-Bike Better? minus plus

It depends on what kind of riding experience you are looking for. For some, a mid-drive electric bike is often considered to be the better option because they offer more efficient power transfer, better hill climbing performance, and more responsive handling by having a more natural riding feel as you pedal.
Additionally, they tend to be lighter than hub motor designs, making them a better choice for longer rides. These eBikes are also more reliable, making them a great option for regular use.
However, they tend to be the most expensive e-bike motor design, so if you’re on a budget, a hub electric motor may be a better option. Ultimately, this depends on your individual needs and preferences.

Do Any Mid-Drive E-Bikes Have a Throttle? minus plus

Yes–some mid-drive eBikes do have a throttle. However, most big electric bike companies tend to rely solely on pedal-assist for their mid-drive eBikes, because when you install a throttle on a mid-drive electric bike, the chain wear and tension might be too great. This could lead to a broken chain and render the bike inoperable, hindering the overall performance.
