Summary of Reviews

We have read all expert and user reviews on the Aventon Sinch. In summary, this is what cyclists think.

13 reasons to buy

  • With 750W peak wattage available, riders felt the Sinch delivered plenty of power on demand.
  • Aventon says the Sinch will fit riders from 5’0” to 6’3” in height.
  • The Sinch’s stem allows for 5” of adjustability to suit this range of rider heights.
  • With a concealed battery and hydroformed aluminum frame, riders and reviewers appreciate the Sinch’s appearance.
  • The Sinch’s battery is lockable and removable for security or charging off the bike.
  • The Sinch’s RST Guide Suspension fork offers 45mm of travel, adjustable compression and lockout.
  • Fat 4” Kenda Krusade tires are versatile and can be run at low pressures for riding on soft surfaces.
  • Bigger owners, weighing up to 180lb and reaching 6”, feel the Sinch is a good fit.
  • Owners said the Sinch’s wide Velo saddle was very comfortable.
  • The Sinch arrives mostly assembled.
  • Riders were satisfied with the Sinch’s Tektro mechanical disc brakes.
  • The Sinch is backed by a 1-year warranty for the bike and a lifetime warranty for the frame.
  • The Sinch’s monochrome LCD display is clear to read and provides a 10-bar battery indicator.

7 reasons not to buy

  • The Sinch does not latch when folded and might be too awkward for public transport.
  • At 68 lb, with folding mechanisms and front suspension, reviewers describe the Sinch as, "fairly hefty" and, "on the heavier side".
  • Reviewers found the Sinch’s 14-28 tooth cassette resulted in a limited gear range.
  • Significant motor noise can be heard when riding the Sinch.
  • One reviewer felt the Sinch’s brake levers could be improved with adjustable reach.
  • Some riders struck their legs against the Sinch’s frame hinge.
  • The Sinch’s M5 display unit randomly resets the odometer.

Bottom line

The Sinch is a compact fat-tire e-bike that folds down for storage in your apartment, car, attic or bug-out bunker. Owners and reviewers were impressed with the bike’s styling, power, battery life and comfortable ride. There is no clasp to secure the bike when folded and reviewers stress that it is probably too large and unwieldy to carry on public transport. Earlier models could not be activated via the throttle-only from a dead stop, but this issue has been rectified as of 2021, bringing the Sinch in line with most competing e-bikes.

Aventon Sinch Review

So much power from the motor, we just flew right up to that top speed… and super-stable. The frame is so gigantic that you don’t really get any frame-flex… the fat tires are almost equivalent to rear suspension… I had a blast riding it.

Aventon Sinch Review: One Fat Tire Electric Bike That Is Different Than All the Others

You get a lot of bang for your buck here. There are certainly cheaper folding, fat-tire bikes out there but not with this level of quality.

Aventon Sinch Folding Fat Tire eBike 20mph | 750w | 48V 13.4Ah Battery

I’m liking the look and most of the specs… In its folded state this bike (and really all folding fat-tire e-bikes) is smaller but not what I would really call ‘ultra-compact’… if you’ve never ridden an e-bike with 20” x 4.0” fat tires, it’s as close to a two-wheel version of a go-kart as you can get, and I mean loads of fun.

This is gonna be good for someone who wants kind of a higher-quality, kind of a higher-end, folding, fat-tired bike but still at a very reasonable price-point.

I Bought the Aventon Sinch From My Review Video, Then Broke It 3 Days Later

The second day of owning the bike, I had it folded up in a corner and it actually fell over and broke the M5 display… kind like bent like a banana… I unlocked the top speed so I hit 28 miles per hour on it… I’m very happy with the front shock absorber… overall, for 60 miles or so with the Aventon Sinch, very happy!
