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!

6 reasons not to buy

  • Several owners say the plastic mounting clip breaks easily and after little use.

  • On its brightest setting, this light has a runtime of only one hour.

Bottom line

Knog’s Blinder Road 400 is a front bike light with four modes and high and low settings. It fits 22–35mm round and aero handlebars. Owners and testers deem it sturdy and easy to use, but some say the mounting clip is fragile. The eye-catching flashing patterns are considered effective in urban settings, but the light isn't bright enough for high-speed rides in unlit areas. Short run times also limit this light's utility. Overall, testers consider the Knog Blinder Road 400 a good be-seen light but say similar, cheaper lights offer better value.
