We didn't call this ebike the Sinch for no reason. Foldable, portable, storable, powerful, comfortable, and ready for anything, the Sinch folding electric bike lives up to the definition of "doing it with ease". Your Sinch compact electric bike will fit in your closet and under your desk, meaning it's almost infinitely portable! Making this electric bike foldable means that 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!

Fantastic e-Bike

I truly love this eBike. Extremely well built and it looks amazing in person. It has a nice smooth ride. It was worth every penny. I’m 6 foot and 215 pounds and it accommodates me perfectly. I highly recommend this folding eBike.

The best of all worlds, but maybe could use more power?

I love everything about this bike except that I'm 230 pounds, recently have had a total knee replacement (I got this bike to help with the rehab). I cannot yet pedal very much and have to reply on the motor/"Throttle". Using motor only the bike can only go 8 miles per hour, sometimes 5 or so going up some of the 7% and 9% roads/hills in my neighborhood (in Connecticut).

Since the Since has a 500 watt motor, I needed more power for my weight and these hills.

Accordingly, I swapped my Since Step-Through for an Aventure Step-Through, which has a 750 watt motor (with 1000 watts peak)

The quality of both bikes is superb and using FedEx, the bikes arrived without shipping damage. But several bolts were missing.

Hi Dave,

Thank you so much for your review! We appreciate you and your support!

2nd verse better than the first

Purchased my 2nd Sinch in March 2022. This time it was the Red step through. Previous purchase was the 2021 step over. Wow! Where do I start? The step over model was the most fun I have had on a bike in the last 30 years... until I bought the step through. Everything is just a little better. The frame geometry is even more comfortable, the tires quiet and cushy, the handling responsive, the gearing and brakes smooth and quiet, folding is easy, battery removal easy, and obviously getting off and on is easy with the step through frame. Construction of the previous model was great, the construction and attention to detail on the new step through is over the top. The pedal assist has been tuned to make the take off smoother, and I have over all better control of my peddle assist levels, and shifting.

Put over 900 miles on the step over. Already have 50 on the step through. Have thoroughly ridden and tested both models. I am 5'11" and 290lb and this bike performs great. Not just on flat ground, but on hills as well. The upright riding position allows me to see all around me and even easily glance up to see the occasional eagle or hawk. I love riding this bike, and really look forward to every opportunity to get on it.
