The Mountain Bikers eMTBLiving in uncharted territory, the Relay is a lightweight, long travel, modular mountain bike. We have always wanted a bike that could provide both an electric and non-electric experience in one chassis. The Relay is light, efficient, and quiet. This provides a more intuitive and natural feel on trail than many would expect from an eMTB. The Relay is here and ready to meet all of your mountain biking needs. Going for a rip with friends on eMTB's? Power it up and head out. Going for a rip with some friends on mountain bikes? Simply remove the battery and hit the trail with no tools required. The Relay does it all. Giddy-Up Suspension DesignWe want to make it as easy as possible to experience great rear suspension performance. The GiddyUp suspension system is designed to behave intuitively across a broad range of setup. Because, we get it, sometimes you just want to grab your bike and GiddyUp, without checking your setup. When you do, it will always feel good. The GiddyUp suspension layout provides 160mm of travel from a 205 x 60mm shock, or 170mm of travel from a 205 x 65mm shock, and is tuned to work correctly with both air and coil. Riders are able to add or remove volume spacers in the rear air shock to suit their individual riding style and there is plenty of bottom out control with air or coil shocks when things get rowdy. With nearly 26% progression and an E-bike specific version of our GiddyUp suspension kinematic, the Relay has an excellent balance of support and small bump sensitivity. The Relay suspension is tuned for maximum traction that enhances both descending and climbing experiences, while delivering a bottomless ride feel. A suggested sag range of 28 - 34% allows the rider to tune the feel of the bike; from a firm and snappy jump and slash mode, to a more supple and active full on party mode. Wherever you end up, you can focus on the trail without remotes, levers or knobs. Just grab your bike and GiddyUp.
