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 Big Cobber Front. In summary, this is what cyclists think.

9 reasons to buy

  • The Knog Big Cobber's elastic silicone straps are easy to mount.
  • This light comes with three mounts, including for standard bars, aero bars, and head tubes.
  • The Big Cobber Front offers excellent side-on visibility thanks to its curved design.
  • This front light is bright enough for being seen during the day.
  • The integrated USB-A connector offers cable-free charging, but most find it necessary to use the included cable.
  • The quick-release mount allows quick attachment and removal.
  • The modes are customizable in Knog’s Modemaker app.
  • The Big Cobber has an IP67 rating, meaning it should be waterproof.
  • This light remembers the last mode used.

3 reasons not to buy

  • One owner's light stops working after a few months. Another owner's stops working after two weeks, but a replacement is provided.
  • At 3.66” long, the Big Cobber occupies significant handlebar space.
  • Two owners report the integrated USB connector breaking.

Bottom line

The 470-lumen Knog Big Cobber Front light is the largest in the brand's range. It's deemed suitable for daytime use, and the side-on visibility earns praise. Modes are customizable in the app, including activating the handy "eye saver" mode. Two buyers report the light failing after only a short period, though these appear to be isolated cases. Overall, experts appreciate the handy features and shape, but its large, space-hogging size may deter some. The smaller Mid Cobber seems to be the more popular choice among cyclists.

Knog Cobber – The Best Light to Make You Visible / Cycling Equipment [Spanish]

It’s worth mentioning that it does meet the battery life it mentions; mine has lasted up to six hours at maximum intensity, and it has worked quite well.
