Razor EcoSmart Metro HD vs Hiboy U2 Pro Seated E-Bike

The Hiboy U2 Pro is the stronger choice for most riders. It has a 750W motor (810W peak), a 48V 13Ah lithium battery with up to 34 miles of range, dual disc brakes, rear suspension and 16x4-inch fat tires, and a 265 lb capacity. The Razor EcoSmart Metro HD is a simpler steel-framed scooter with a 350W rear hub motor, a sealed lead-acid battery, a single rear hand brake and no suspension; owners like its upright seated ride and U-shaped deck, but it is slower, shorter-range and heavier for its power. The U2 Pro's 4.8/5 rating from 47 ratings reflects solid owner satisfaction; the Razor's lead-acid battery and lack of suspension are its main drawbacks.

  • Choose the Razor EcoSmart Metro HD if you want a simple, upright seated scooter for short paved commutes and prefer a steel frame and low-maintenance lead-acid setup over speed and range.
  • Choose the Hiboy U2 Pro if you need more power, range, hill climbing, suspension and dual disc brakes for errands, hills or rougher pavement.

What reviewers say

Hiboy U2 Pro Seated E-Bike

  • 4.8 / 547 ratings

Buyers rate the U2 Pro 4.8 out of 5 from 47 ratings and describe it as powerful, smooth and well made. They say it handles bumps, hills and gravel without trouble and holds up on flat rides. Complaints center on stripped fender screws and reduced battery life on hills.

What people mention
  • Ride comfortPraisedOwners say the fat tires and rear suspension smooth out cracked sidewalks and gravel.
  • PowerPraisedBuyers report plenty of power for hills and loaded trips.
  • Battery rangeMixedRange holds up on flat riding but drops on hills, owners say.
  • AssemblyPraisedBuyers say it was well packaged and easy to put together.

Questions and answers

Which is better for hills?
The Hiboy U2 Pro. Its 750W motor and 20-degree climbing rating handle grades the Razor's 350W motor cannot, and the rear suspension keeps the ride steadier on the way up.
Which lasts longer on a charge?
The U2 Pro by a wide margin, with up to 34 miles against the Razor's 12. The Razor's lead-acid pack also degrades faster with age than the U2 Pro's lithium battery.
Is the U2 Pro worth stepping up to from the Razor?
Yes for most riders. You get more than double the range, a much stronger motor, dual disc brakes, suspension and fat tires, at the cost of extra weight and longer charging.
Which is better for rough pavement or gravel?
The U2 Pro. Its 16x4-inch fat tires and rear suspension absorb cracks and gravel; the Razor has no suspension and is rated for paved roads only.
Which is easier to carry or store?
The Razor is lighter at about 73 lb against about 81 lb, but both are heavy. The U2 Pro's larger frame takes more room, so plan for ground-level storage for either.
Do either have smart features?
No. Neither has an app or connectivity; the U2 Pro is deliberately simple, and the Razor is a basic seated scooter.
