Motor Bash Cover 2

We totally redesigned the motor cover, taking the opportunity to improve its strength and functionality since we had to redesign the frame in the motor mounting area to accommodate the new motor. The new cover is now a one-piece item, making it much stronger to function effectively as a skid plate. We’ve also re-positioned the two mounting screws to protect them from mud and dirt buildup, ensuring they remain easy to remove. Additionally, the redesigned shape offers increased clearance under the bottom bracket.

For the material, we used PA66 / Nylon 66, which is recyclable. PA66, or Nylon 66, is a synthetic polymer created through the polymerization of hexamethylenediamine and adipic acid. Renowned for its excellent mechanical strength, chemical resistance, and heat tolerance, Nylon 66 is widely used in industries such as automotive, aerospace, and consumer electronics. By using Nylon 66, we guarantee the high-level performance and durability that our customers expect, while also considering environmental factors.

Equipping you with everything you need—and more—to keep your bike perfectly dialed

Kinematics

The suspension kinematics, designed by Cascades Components, are in a class of their own. Our bike offers the perfect combination of suppleness and support to ensure everyone from the most discerning rider to the weekend warrior are obtaining maximum performance out of all of the floating points in this tried and tested dual link suspension platform.

Plus don't forget to read about the flexibility to adjust your amount of rear travel. We just didnt want to force you to only ride your bike one way. What if you move to a new area with new terrain or what if you simply want to set your bike up appropriately for the kind of terrain you are riding any given sunday? We worked hard to make sure that is an option, so please use it!

Ebike Flip Chip 1
Rear Travel Adjustment
Mess with your amount of squish

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 180mm on this LS160 The two main settings and shock information on the stock build are as follows:

  • 230mm x 65mm flip chip in ST (short travel) = 161mm travel
  • 230mm x 65mm flip chip in LT (long travel) = 182mm travel

We'll give you some more too think about as there are a number of 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 trail bike:

  • 230mm x 62.5mm flip chip in LT = 172mm rear travel which he pairs with a 170mm fork.
Headset
Set Your perfect Reach number
Straight 56mm head tube

By using a straight head tube we preserve a fair bit of cockpit optionality. Set it up with a ZS56-ZS56 or ZS56-EC56 press-in headset brings with it the ability for you to run a variety of reach adjust and angle adjust headsets. 

This allows adjustments of +/-5mm with a single crown fork from stock or up to +/-10mm with a DH fork.

This batch of RS 180 complete e-bikes all ship with a reach adjust head set pre installed allowing you to reap all the benefits of having a straight head tube design. You can also run aftermarket anglesets to adjust HT angles since this head tube does not discriminate against the lowest and slackest setups if that is what your heart desires.

 

UDH
keep downtime to a minimum
Sram's UDH (universal deraileur hanger)

All of Crestline's bikes use a 148 x 12 rear end and a Sram UDH. This means Sram T-type transmission can be used on all our bikes. You can also swap wheels between bikes easily and also minimize any downtime cause by those pesky things that happen when you ride these bikes the way they are designed to be ridden. Bring on the rocks strikes and wheel pingers. If you need to replace a hanger or throw on a wheel from another bike to keep rolling you'll be back out in no time.

Water bottle and tool
never end up parched
Carry all the essentials

We made sure we had space in the frame to add water bottle mounts as well as mounts for tool storage. This way you can make sure you always have what you need with you and you'll never be left out to dry!

Size & Configuration dependent rear wheels and chain stay lengths
No compromise, one piece, 27.5 and 29 Rear Triangles

Balance is everything and you deserve the correct wheel size combination for your size setup. You also deserve the right to choose what you want to run. Our bikes are spec'd as we recommend them to be ridden but we wont force you to keep them that way. After market rear triangles are available upon request. We're just an email away! 27.5 and 29 RT's are interchangeable and will fit any size bike. *It is however important to note that if you wish to change rear wheel size from your initial configuration, you will need to be sure to purchase the appropriate swingarm to do so.
