Trek Borrego+ 4 — E-Commuter Bike

Midstep frame designed for easy on/off mounting and an upright, comfortable riding position

500W rear-hub motor with 90Nm of torque and throttle assist, offering three levels of pedal support from eco to high

720Wh removable battery for easy charging and transport

Up to 112 km of range per charge (varies with assist level, terrain, and rider weight)

8-speed drivetrain paired with hydraulic disc brakes

Custom 26x4" fat tires with puncture protection and an 80mm front suspension fork

Heavy-duty MIK-compatible rear rack (27kg rated), full front and rear fenders, and integrated front/rear lights with turn signals and a brake light that stays on for up to 3 hours after the battery depletes

Trek Central app compatibility for eLock security, on-the-fly motor tuning, personalized range estimates, and firmware updates 

The Borrego+ 4 suits riders who want one bike that can comfortably handle grocery runs, neighbourhood commutes, and longer weekend rides without breaking a sweat. It's a strong fit for commuters who want throttle assist for hills and stoplight starts, and for anyone who wants the stability of fat tires for gravel, packed snow, or rougher pathways around town. Riders who value cargo capacity and all-weather practicality — rack, fenders, and integrated lighting included — will get the most out of this build.

Our team at Fresh Air will help you find the right fit in-store at both Kelowna locations. Stop by to work with one of our experienced staff members, or call 250-763-3425.

As a Trek dealer, our team can walk you through the Trek Central app setup, help you get comfortable switching between throttle and pedal-assist modes, and check that your fenders and rack are properly secured for the loads you plan to carry. We'll also confirm your tire pressure is dialled for the terrain you ride most, whether that's pavement, the Okanagan Rail Trail, or looser surfaces. We offer ongoing e-bike servicing, firmware updates through Trek Central, and year-round advice to keep your Borrego+ 4 running the way it should.

What size Trek Borrego+ 4 do I need?
Sizing depends on your height and inseam, and Trek's size guidance is available on their geometry chart (see above — currently flagged for verification). The best way to get it right is to come into either Fresh Air location, where our team can measure you up and get you on the correct frame size in person.

Is the Trek Borrego+ 4 right for riding the Okanagan Rail Trail or commuting around Kelowna?
Yes — the Borrego+ 4's fat tires, upright riding position, and throttle assist make it a great match for the Okanagan Rail Trail, as well as day-to-day commuting between Kelowna neighbourhoods where stop-and-go riding and varied surfaces are common.

How far can I ride on a single charge, and what factors affect range?
Trek states up to 112 km of range from the 720Wh battery, though actual range depends on assist level, throttle use, rider weight, terrain, and temperature. Riding in eco mode on flat ground will get you closer to the top end of that range than riding in high assist or relying heavily on the throttle.
