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!

The Mongoose Juneau is a fat bike with a slim price. Its 4” tires allow riders to pedal over sand, snow and dirt without issue. The bike comes in one size. Riders taller than 6’ find it small. The bottom bracket noise and chain slap both annoyed riders. Other issues, including faulty frame welds and poor crank durability, were common complaints.
