Our take on the Electric Mountain Bike 500W 21 Speed U57542

The Vivi M026SH is a 26-inch electric mountain bike with a 500W rear hub motor that peaks at 750W and a 48V 7.8Ah (374.4Wh) battery. It pairs a 21-speed drivetrain, front suspension and front and rear disc brakes with an aluminum frame, an LED headlight and an electric bell. Top assist speed is about 20 mph and Vivi claims 50+ miles of range. It suits riders who want a low-cost entry into assisted off-road and commuting riding; at this level, expect a heavier build and a smaller battery than pricier hub-drive rivals, and check the range claim against real-world reports.

Best forBudget-minded first-time e-bike buyersLight trail and gravel ridingCommuting with pedal assistRiders who want a throttle-style boost on hills
Pros
  • 500W motor with 750W peak for hill climbs
  • 21-speed gearing gives wide range with and without assist

  • LED headlight and electric bell included
Cons
  • 374.4Wh battery is small next to many rivals
  • 50+ mile range claim assumes low assist and light rider
  • Heavier than a plain mountain bike, so pedaling unassisted is hard work
  • Hub motor and basic suspension limit serious trail use
  • Assembly and tuning needed out of the box

What reviewers say

Owner feedback on this class of budget hub-drive e-MTB is mixed: riders like the power for the money and the 21-speed range, but report range falling well short of the claim at higher assist and note the weight and basic components.

What people mention
  • Motor powerPraisedRiders say the 500W hub motor pulls strongly uphill and off the line.
  • Battery rangeCriticisedOwners report the 50+ mile figure only holds at low assist with a light rider.
  • WeightMixedThe bike is manageable on assist but heavy to pedal or carry without it.
  • GearingPraisedThe 21-speed drivetrain lets riders keep going when the battery is drained.
  • AssemblyCriticisedBuyers mention time needed to assemble and adjust brakes and derailleurs.

Questions and answers

How fast does the Vivi M026SH go?
Motor assist tops out around 20 mph. Above that you pedal it like a normal mountain bike.
What is the real range on a charge?
Vivi claims 50+ miles, but that assumes low assist and a light rider. Expect noticeably less at high assist or on hills.
Can I ride it with the battery off?
Yes. The 21-speed gearing makes unassisted riding possible, though the bike is heavy.
What size rider does the 26-inch frame fit?
It is a 26-inch wheel adult bike aimed at average-height riders; check the standover height before buying if you are very short or tall.
Does it come with lights and a bell?
Yes, an LED headlight and an electric bell are included.
Is it good for serious mountain trails?
It handles light trails and gravel, but the hub motor and basic suspension are not built for aggressive downhill riding.
