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 Knog Frog Front. In summary, this is what cyclists think.

5 reasons to buy

  • Owners appreciate the Frog’s nine modes.
  • Reviewers say the lens shape ensures good side-on visibility.
  • Testers praise the eye-catching flashing patterns.
  • The Frog mounts on handlebars or frame tubing up to 32mm in diameter.
  • The sticky silicone casing keeps the light firmly in place when mounted.

3 reasons not to buy

  • Several owners report issues shortly after purchase, such as the silicone detaching from the lens and a broken button.
  • The battery indicator is only visible when the light is off, making it difficult to determine charge status while riding.
  • An expert says the small button is difficult to locate and press while wearing gloves.

Bottom line

The Knog Frog Front is a 40-lumen be-seen headlight with nine modes. It's rechargeable, but the USB-C cable isn't included. It fits handlebars or tubing 22.2mm to 32mm. Owners and testers praise the choice of modes, eye-catching flashing patterns, and good side-on visibility. Unlike real frogs, the Knog Frog can't be submerged in water. The silicone casing provides grip, but some find it's easily breakable, and the small button is hard to locate with gloves. While experts say the Frog does a good job as a be-seen front light, one feels it's overpriced.
