Rail 7 is a long-travel electric mountain bike built for ripping the big stuff. It features the same high-end trail tech as our analog trail bikes, an upgraded fork, drivetrain, battery, and more, plus a powerful Bosch drive system thats basically like having your own shuttle.
  • Rail Gen 3 is built for big adventures, with Boschs smart system that packs in all the power you need, and a Bluetooth-connected LED remote thats sleek and intuitive
  • Treks Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy to remove the battery without tools and lets you mount a water bottle cage
  • Rail keeps your cockpit tidy by skipping a display, but smart system makes it easy to add one
  • The controller has Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
  • Made with the same hard-charging frame tech as our amazing trail bikes, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness, and Active Braking Pivot (ABP)

Bosch Performance Line CX motor

Bosch Performance Line CX sets the standard for eMTB performance with up to 85Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.

Removable Integrated Battery

RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security, or just easier charging.

Bosch LED Remote

The Bosch smart system LED remote lets you easily change assist modes, activate walk mode, or turn on optional lights. The bright LEDs are easy to see in any light, and show you your battery level and assist mode at a glance.

Bosch Smart System

Bosch smart system gives you an eMTB thats more connected than ever. The LED remote connects with Bosch eBike Flow app so you can get ride stats, adjust settings, and perform system updates. Plus, Bluetooth connectivity makes it easy to add a display if you want to make it easier to see your ride data.

Active Braking Pivot

Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

Good value, very useful for go kart wiring
Size: 100ft, Style: 6C-18AWG
It's a good spool to have around to wire lights and things on the go karts. Also came in handy when I had to patch a bit of melted wire harness on the tail of the old Dodge.

Beware! Very thick wire
Size: 50ft, Style: 6C-18AWG
I'm not going to ding the product, because it's totally what it says it is. I didn't look at the diagrams to see that this wire is 10mm wide. Almost half an inch. Waaaay to thick for the project I needed it for.

Fantastic to do 1 run and power multiple loads
Size: 30ft, Style: 6C-18AWG
Great for wiring up multiple loads. In my case multiple lighting with different switches so that I can turn them on independently from one another.
