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 KBO K Series. In summary, this is what cyclists think.

13 reasons to buy

  • Owners and experts agree the K Series offers good value at this price.
  • The KBO K Series is available in both step-over (K1) and step-through (K2) frames.
  • Experts say the 500W motor provides ample power and “zippy” performance.
  • The K Series folds to a compact size of 35" x 20" x 28".
  • At 55lb, the K Series is relatively lightweight for a budget electric bike.
  • Reviewers deem the pedal-assisted hill climbing "respectable."
  • The 52t chainring makes it possible to pedal at the max speed.
  • Testers say the suspension fork effectively absorbs bumps.
  • Reviewers commend the “grippy” 3” tires for their stability and cushion on uneven terrain.
  • Experts praise the “nimble” handling for navigating tight spaces.
  • According to testers, the bike pedals well without assistance.
  • The K1 and K2 come mostly assembled and include accessories such as fenders, a rack rated for 55lb, a bell, and a headlight.
  • The K Series is available in six colorways.

8 reasons not to buy

  • Testers find the brake levers require significant force to engage.
  • The externally routed cabling is unsightly.
  • Both throttle and pedal assist exhibit a slight "jerkiness” and noticeable lag.
  • Reviewers report the “thin” and “hard” seat as uncomfortable on longer rides
  • The suspension fork lacks adjustment and lockout.
  • The K Series doesn't come with a taillight.
  • Two reviewers report that the front brakes require adjustment after assembly.
  • One tester notes that the odometer shows lower mileage than actually traveled.

Bottom line

The KBO K Series is a budget 500W electric bike available as a step-over (K1) or step-through (K2). The "simple" folding mechanism, compact folded dimensions, relatively low weight, and commuter accessories make it a practical urban option. However, it lacks comfort for longer commutes, the brakes require a lot of force at the lever, and motor power is jerky and slow to engage. Despite these drawbacks, the K Series' low price makes it a reasonable option for commuters on a budget.

KBO K2 A Great First E-Bike

The KBO K2 is a great little folding e-bike for someone looking for their first e-bike. It’s powerful, but not overly powerful, which will help to keep you safe.
