Bike Size Charts

BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.

We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.

It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.

If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews

We have read all expert and user reviews on the isinwheel U5. In summary, this is what cyclists think.

8 reasons to buy

  • Owners and testers from 5' to 6'4" find the U5 comfortable thanks to the 9.4" of seat height adjustment and 5.6" of handlebar adjustment.
  • The U5's weight of 48.5lb means it's more portable than other folding e-bikes at this price point.
  • A tester is pleased with the throttle's responsiveness.
  • The U5 comes with a headlight and taillight with brake activation and the frame has mounts for a front basket, rear rack, and fenders.
  • Testers find the mechanical disc brakes provide ample stopping power.
  • Using mostly throttle, a reviewer gets 22.7 miles of range in stop-and-go city traffic.
  • One reviewer says the U5 is very maneuverable.
  • Experts are impressed by the inclusion of cruise control at this price.

14 reasons not to buy

  • Some owners and a reviewer receive a U5 with a 350W motor instead of the claimed 500W unit.
  • Buyers complain the user manual is difficult to understand and lacks key information about assembly and operation. One buyer receives the wrong manual.
  • A tester reports an eight-second delay for pedal assist to kick in.
  • The keyhole's position on the underside of the frame behind the cabling is awkward to access.
  • Multiple buyers receive bikes with faulty batteries or displays.
  • Experts and owners find the ride harsh over bumps.
  • isinwheel owners are disappointed by the slow response time from customer support.
  • Owners and a tester complain of squeaky brakes.
  • A reviewer reports play in the stem's folding mechanism on their test bike, resulting in a noise while riding.
  • The 10-bar battery indicator is difficult to read and inaccurate, according to an expert.
  • One tester experiences a battery issue, causing a drastic loss of power on the first test ride.
  • A reviewer finds the folding hinges tend to get stuck, making it hard to fold the bike. An owner also finds the folding process difficult.
  • Owners and testers find the saddle uncomfortable.
  • The below-average IPX4 water resistance means the U5 shouldn't be ridden in heavy rain.

Bottom line

The isinwheel U5 is a budget folding e-bike with a 500W motor and 374.4Wh battery. The wide height range, relatively low weight, agile handling, and responsive throttle earn praise from testers. Buyers complain about receiving a 350W motor instead of the listed 500W motor. Other criticisms include a confusing and inadequate owner's manual, awkward keyhole positioning, a harsh ride over bumps, and severely delayed PAS activation. Additionally, buyers and testers receive bikes with faulty electronics, hinges that stick, and squeaky brakes. isinwheel replaces faulty electronics but is slow to respond to customers. Overall, it seems the U5's quality matches its low price.

isinwheel U5 E-Bike – For [Price] Here’s What I Think!

It’s definitely a budget e-bike, but it does the work especially if you’re going to commute locally. I’d say no more than five miles of travel, between five to six miles each way, that’s going to be where this thing shines.
