We didn't call this ebike the Sinch for no reason. Foldable, portable, storable, powerful, comfortable, and ready for anything, the Sinch lives up to the definition of "doing it with ease". Your Sinch will fit in your closet and under your desk, meaning it's almost infinitely portable! It'll even fit in the trunk of your car or easily into your RV so you can take it anywhere with you. With 4" fat tires and a front suspension fork this ebike is ready to both cruise the pavements and conquer the trails!
The powerful motor and stealthily integrated battery mean that you'll never be short of power, and 5 levels of pedal assist and a no-nonsense, no-need-to-pedal throttle mean that you can go as hard or as light as you want. Cruise around town or through the park on this and you're sure be turning heads!

Sinch ships as a Class II ebike, with pedal assist and throttle. If you are riding on private property or in an area without ebike speed restrictions, the speed limit can be modified in the settings, and Sinch's powerful motor can go up to about 4 MPH above the factory set top speed. Sinch can also operate with the throttle unplugged and removed, should you want to ride in an area where throttles are not allowed.
Aventon ebikes are built to the IPX4 water-resistant standard. IPX4 means that your bike is resistant to water splashes from any direction. This means it’s OK to ride or park your ebike in the rain. It won’t be harmed by spray from a wet road or raindrops. Your ebike is not intended to be submerged or subjected to a pressurized spray. Don’t use a pressure washer or sprayer to clean your ebike.

The specific warranty covering your Aventon bicycle is governed by the law of the state or country in which it was purchased, and applies only to bicycles purchased from Authorized Aventon Retailers or directly from Aventon.
FRAMES AND FORKS: Aventon frames made from steel or aluminum (Mataro, Cordoba, Andreas, Kijote, Pace e-bikes) are warranted by Aventon Bikes, 1950 S-Grove Ave. Unit B, Ontario, CA 91761 against manufacturing defects in materials and/or workmanship for the lifetime of the original owner. Aventon frames made from carbon fiber (Ultro) carry a 5 year warranty for manufacturing defects in materials and/or workmanship.
COMPONENTS: All other components, frame fixtures and finishes (paint and decals) are warranted against manufacturing defects in materials and/or workmanship for a period of one year from the date of original retail purchase. Forks (other than those made by Aventon -for example, a Rockshox suspension fork) are not covered by this limited warranty, but are separately covered by the stated warranty of their manufacturer. Stripped threads due to operator error during assembly are not covered by this warranty.
TERMS OF LIMITED WARRANTY: This limited warranty is not meant to suggest or imply that the bicycle cannot be broken or will last forever. It does mean that the bicycle is covered subject to the terms of the limited warranty. This limited warranty applies only to the original owner of an Aventon bicycle and is not transferable to subsequent owners. This limited warranty is void if the bicycle is subjected to abuse, neglect, improper repair, improper maintenance, alteration, modification, an accident or other abnormal, excessive, or improper use. This limited warranty applies only to bicycles purchased in fully assembled and adjusted condition from Authorized Aventon Retailers or other outlets specifically authorized by Aventon to distribute Aventon bicycles. Damage resulting from normal wear and tear, including the results of fatigue, is not covered. Fatigue damage is a symptom of the frame being worn out through normal use. It is one kind of normal wear and tear, and it is the owner’s responsibility to inspect his/her bicycle. Damage resulting from improper assembly or maintenance, or from installation of parts and accessories not compatible with the Aventon bicycle, is not covered. All labor charges for warranty service are the responsibility of the bicycle’s owner. In the event that the processing of a warranty claim requires shipping, any such shipping charges are the responsibility of the bicycle's owner. During the duration of this limited warranty, Aventon will either repair any defective frame or component, or, at our option, replace any defective frame or component with the same or most nearly comparable model or component then available. THIS IS THE EXCLUSIVE REMEDY UNDER THIS WARRANTY. ANY AND ALL OTHER REMEDIES AND DAMAGES THAT MAY OTHERWISE BE APPLICABLE ARE EXCLUDED, INCLUDING, BUT NOT LIMITED TO, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR PUNITIVE DAMAGES. THIS IS THE ONLY WARRANTY MADE BY AVENTON ON ITS FRAMES AND COMPONENTS, AND THERE ARE NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION HEREIN. ANY WARRANTIES THAT MAY OTHERWISE BE IMPLIED BY LAW INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, ARE EXCLUDED. This Limited Warranty gives the consumer specific legal rights. The consumer may also have other legal rights which vary from state to state or country to country. Some states and countries do not allow the exclusion or limitation of incidental or consequential damages or warranties, so the above limitations or exclusions may not apply to you. If it is determined by a court of competent jurisdiction that a certain provision of this limited warranty does not apply, such determination shall not affect any other provision of this limited warranty and all other provisions shall remain in effect.
