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!

One tester told of Supernova sending them out a replacement light as they toured through Azerbaijan!

Supernova E3 Pro 2 Dynamo Front Light

This is about as good as it gets. A well-built, rebuildable unit with a long warranty and near-perfect beam pattern and performance for road use. You’ll never have to worry about where your lights are, or whether they’re charged, ever again.

Supernova E3 Pro 2 Bike Light Review [German]

Although the Supernova E3 Pro 2 doesn’t quite get a very good rating in the test, it’s still a good choice. The “made in Germany” seal alone guarantees quality construction.

My Audax Dynamo Light Setup

When you’re on a big ride at night, you’ve got a lot of hours of darkness and sometimes battery lights won’t last long enough, so I got myself a dynamo. It’s 1 year old, it’s done six to seven thousand miles. I don’t think it’s completely watertight, but it still works.

Dynamo Powered – Supernova E3 Pro 2 Headlight

This is a standard M5 mount which means that you’re actually going to be able to mount this to just about anything and you can adjust the multimount to be able to work with a whole bunch of different setups.
