    How far can I go on a single charge? The range depends on each bike model and several other factors such as the weight of the rider, the type grade of he terrain, wind speed and direction, tire pressure, temperature, cargo, etc. The average range on a fully charged battery is between 30 and 65 Miles. To get the best possible range the rider must pedal along with the P.A.S. Riding on throttle alone will considerably reduce the milage.
What's maximum speed? All models have a limited speed of 20 MPH on pedal assist to comply with Class 2 classification, meaning they can be ridden on most public roads and the rider does not require any special license.
How long does it take to fully charge a depleted battery? Typical battery full charging time is 5 hrs.
Do I need a special license or register my vehicle with the DMV? License is not required at this time by law, as long as the ebike is Class1 or Class 2. Insurance is optional but not required by law.
What's the maximum weight capacity? Payload varies depending on the model. Typical maximum payload range on trikes goes from 250 to 330 Lbs, this includes any additional cargo.
What kind of warranty do your trikes have? Each vehicle has a limited warranty for 1 year from the time of the purchase. Consult your warranty terms in your user manual for more details.
What happens if my vehicle requires service or a repair while it is under the warranty? Trikes require similar maintenance than regular bicycles such as chain tension adjustment, lubrication, screws and nuts re-torque etc. However there are certain components that given the case may require directly to the repair shop.
I ordered a completed trike. how is it packed? In most cases, the bike comes with one large box already preassembled, however you would need to install some components such as front wheel, fenders, handlebar and lights. Trikes are usually shipped in 3 boxes and require full assembly.
How long will the order be shipped out? It usually takes from 3-5 days after placing your order.
Where do you ship? We ship inside the continental USA. Shipping to Canada and Mexico would be possible but extra shipping and customs fees would be involved and need to be covered by the purchaser.
Can I stop by your warehouse and pick up my order? Yes. Let us know 48 hrs prior to your planned visit and we will make sure to have your order ready. We also provide fully assembly service with additional cost.
Do you offer any financial help for someone with poor credit? We do not offer any financial help or financing options for customers with poor credit. However, we give extra discount on our demo trikes.
