Crestline RS 75/50 E-Bike, Sram XO T-Type Build, Bosch CX-R Motor, Black/Copper, 29"

Crestline Bikes RS75/50 - 175mm Rear Travel/EMTB

When Crestline Bike Co. let us know what they are up to and making an emtb that was aimed to take on the rowdiest downhill trials that will also be equipped with the Bosch CX Race Motor, we were immediately interested. The Crestline RS75/50 is their long travel ebike that is ready to take on anything you can throw at it. With 175mm of rear travel and 180mm of front travel stock, this long-legged full power e-bike hold nothing back. With a dual-link suspension design that has been tuned and crafted by the experts at Cascade Components, it has quickly become one of our favorite ebike to go ride. Crestline also went to the full distance with every detail on this bike. From being one if not the first bike to ship with the Bosch CX-Race motor and Bluetooth remote system, a removable 750wh battery, integrated display in the top tube and a charging port up high near the headtube to avoid issued with muck and damage from being down low. Other frame details include a straight 56mm headtube so you can adjust the reach with an aftermarket reach adjust headset, size-specific chainstay and rear wheel size, and the ability to swap the bike into it’s shorter travel sibling, the RS50/75.

Sizing on the Crestline bikes fall into a Rider Height system, with an RH-2, RH-3 & RH-4 size to choose from. The RH-2 will be close to most mediums, RH-3 to most larges and RH-4 like most XL frames. As noted you can install an aftermarket headset to adjust the reach +/- 5mm if you desire.

This is the currently available batch of RS 75’s from Crestline Bike Co. This bike will be available in the colorway pictured and features a full SRAM build which includes the new XO T-type transmission drivetrain. The RS 75 bike ships setup with 175mm rear wheel travel combined with a 180mm travel fork. All bikes are fitted with the Bosch CX-R (Race) motor and a 750wh battery along with all the newest bluetooth controller components available from Bosch.

Geometry recommendation is eBike specific as we have found that the bike performs better in a slightly smaller size than one might be encouraged to ride by other brands. The reason for this is to balance the mass you naturally get on the front wheel with a battery in the DT. What this means is that you still get really good weight, and therefore, traction on the front wheel even when running a shorter reach. This allows you to get the most out of an ebike when the weight hinders you the most which we have found is in really steep or tight terrain. We have found this sizing adjustment helps you obtain a more nimble feeling bike and also allows you to get back more when it comes to steep terrain. This is also why we added the option to adjust your reach by using a reach adjust headset. It will help you find that perfect balance.

Crestline chose to manufacture their frames at a trusted factory run by VIP Composites in Vietnam. VIP has been making high-end carbon bikes for decades and the list of bikes that come out of their factory will be very familiar to those in the full-suspension mountain bike world. We used the highest end modulus carbon and layup process offered by VIP on all of our frames to ensure the best strength-to-weight ratios. In order to dial in the correct stiffness, Crestline ran through a number of combinations of different layup options, used on both front and rear triangles, before settling on the combination we ultimately decided to use in the production run.

Rear Travel Adjustment - Crestline worked with Cascade Components on the kinematics on this bike. What has been achieved is the ability to adjust your rear travel from 150mm all the way up to 175mm (thus the model name RS 5075) The two main settings and shock information are as follows: 230mm x 57.5mm flip chip in ST (short travel) = 150mm travel & 230mm x 65mm flip chip in LT (long travel) = 175mm travel

We'll give you one more too think about but there are other many other options you can play with since a 230mm eye to eye shock is available in 57.5 / 60 / 62.5 and 65mm stroke lengths. Here's the way one of the founders likes to run his bike: 230mm x 65mm flip chip in ST = 162mm rear travel
