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 Oraimo Monster 100. In summary, this is what cyclists think.

13 reasons to buy

  • Experts savor the 21-speed Shimano drivetrain, which eliminates ghost pedaling.
  • Testers appreciate how light the 49.6lb Monster 100 is for a budget e-bike.
  • The included 4A charger provides fast charging. The quick-charge feature adds 7 miles of range in 15 minutes.
  • The inflatable saddle has a built-in pump to adjust the firmness.
  • Reviewers say the suspension fork and “comfy” seat provide a smooth ride on bumpy roads.
  • Experts note this bike’s easy steering and good agility.
  • Testers appreciate the grip that the tires provide on varied terrains.
  • Reviewers praise the battery range. One gets 25 miles on mostly flat terrain; another gets over 15 miles at 20mph with 593 feet of elevation.
  • The Monster 100’s acceleration and cruising speed impress testers.
  • Experts say the throttle and pedal assistance are surprisingly responsive for a budget bike.
  • Reviewers relish this bike’s comfort and speed on light trails.
  • The Monster 100 has a 308lb payload capacity.
  • Testers say the Monster 100 pedals similarly to a regular bike with pedal assist off.

6 reasons not to buy

  • The Monster 100’s lack of lights, fenders, and cargo rack limits its utility as a commuter.
  • Experts agree the one-size-only Monster 100 doesn’t suit taller riders. Oraimo rates it for riders from 4’11” to 5’8”.
  • The narrow 2.1” tires, basic suspension fork, and small 350W motor hinder true off-road performance, say testers.
  • Users complain of poor off-road performance given the "mountain bike" marketing.
  • Owners report defective components, frustrating customer support, and the lack of a user manual.
  • One user highlights a problem with torque washers cracking.

Bottom line

Oraimo’s Monster 100 is a budget-priced electric bike with a non-adjustable suspension fork and 350W motor. The acceleration, speed, and range impress, especially given the pricing. Experts also praise the bike’s relatively low weight, “smooth” ride, easy unassisted pedaling, and choice of 3x7-speed gearing. The bike’s off-road skills are limited, and the “compact” frame doesn’t suit riders above 5’8”. Also, commuters will need to spend extra to add lights, fenders, and a cargo rack. But overall, testers deem the Oraimo Monster 100 great value for urban and light-trail duties.

Awesome Bike for the Price! | Oraimo Monster 100

The Oraimo Monster 100 isn’t what I would call a monster of a bike, but that’s really the only thing I didn’t like about it. It’s a legit bike for the price. I’m more than happy with how it held up.

Oraimo Monster 100 Review: A Cheap & Stylish Ride!

The bike doesn’t cost much, but still works really well on urban roads…. and has great features, making it a good competitor in its group… the bike has been equipped with a 21-speed Shimano transmission, which really gives it an edge over others.

Oraimo Monster 100 | Low-Cost Transportation?

If you are on a serious budget, there’s a lot better bikes you can get, but for the money, you’re gonna get rolling, and you can throw this in the back of a car, too.
