Details
We have a couple Sinch's to test ride any time at our shop, and limited number of brand new Sinch's in stock (call for availability). If a bike isn't in stock, we can order any size or color for you. It usually takes 7-14 working days for a special order bike to arrive, then a day or two to build the bike.
We are the same price as Aventon.com and our professional bike builds are free (a $180 value), and we offer free labor on bike repairs for 5 years after purchase. We will take care or you!
The Sinch is a Class 2, 500 W, folding, cruiser. It is a joy to ride, very stable with the 4" road tires, and the styling can't be beat.
Foldable, portable, storable, powerful, comfortable, and always ready for the journey ahead. The Sinch Step-Through electric bike is the epitome of versatility meeting ruggedness. Store it in the trunk of a car or easily into a RV so you can take it anywhere with you as your very own two-wheeled companion. With 4" fat tires, a front suspension fork and a 500W motor, the Sinch ST can effortlessly take on both a relaxing cruise on pavement and a thrilling run on the trails!
