The RS 50/75 pairs 150mm of Rear travel with a 160mm Fork and is a Bosch equipped eBike sporting Cascade Components Kinematics

This is the debut eBike release from Crestline Bike Co. We are essentially an ebike focused brand even though the first bike we released was a DH frame. This example will be available in two models. The RS 50/75 will ship configured with 150mm rear travel combined with a 160mm travel fork. The burlier RS 75/50 will ship configured with 175mm rear travel paired with a 180mm fork. These first editions of the bike will be limited to 50pcs in each configuration, adorned with Ohlins suspension front and rear, and labelled with a limited number badge from 1/50 to 50/50 in each configuration. Both models are fitted with the new BOSCH CX-R (RACE) motor and a 750wh battery along with all the newest components available from Bosch for model year 2023. This includes the system controller and blue tooth mini remote (to get rid of the pesky cables we all hate on the run of the mill eeb cockpit). We also made sure to place the Kiox screen nicely into the TT for you, so no horrible bar mount screens and no internal cable routing. *It should be noted that either bike can be configured in any of these two travel setting with a few changes so the badge will just display how it was configured as it left the factory, but that wont stop anyone from re configuring it. In addition we will offer smaller batteries in 500wh or 625wh as Bosch makes them available for this system. More information on all these options plus more will be detailed below. 


Our eBikes will be available as complete bikes only! In the interest of getting these bikes out into the world for you all to enjoy as soon as possible, we are giving people the chance pre purchase a bike and secure that you get one from the first batch of 30 examples that are scheduled to start shipping to customers on March 10th. Please be sure to read below to see the exact specs of the build on offer. *Pictures do not show the bikes built with the parts they will ship with so it is important for you to read the spec list before making your purchase. (Colorway for the RS 50/75 is White Front Triangle with Black Rear Triangle, no colors on top tube like custom bike in pictures but looks very similar!)

If the size you want shows as “In stock” – This means you can get one shipping March 2023.

If the size you want shows as “Available to backorder” – We are sorry but this means you missed the first small batch but can get yourself down for May shipping by emailing us at

We are getting a number of questions about “frame only”. Right now we are only doing complete bikes. We will continue to explore the viability of frame only and keep you all posted but for now we have no plans to do so. – Sorry
