Bike Rentals, Repairs & Local Services

You don’t have to bring your own bike to enjoy Winter Park’s trails. Local shops in both Winter Park and Fraser provide high-quality rentals, professional repair services, and friendly trail advice. Choose from cross-country, enduro, or downhill models depending on your riding goals.

Tips for Rentals:

  • Reserve bikes early during peak summer months.

  • Choose the right suspension setup for your route.

  • Rent protective gear for downhill or park riding.

  • Ask local mechanics for trail condition updates before heading out.


When to Ride

  • Best Season: Late June through mid-September offers dry trails and ideal temps.

  • Spring (May–June): Trails at higher elevations may still hold snow or mud.

  • Fall (September–October): Cooler weather and golden aspens make for unforgettable rides.

  • Winter: Trails are generally closed to mountain biking but open for fat biking or Nordic skiing.

Plan for afternoon thunderstorms in midsummer — start early and aim to finish rides before 2:00 p.m.


Safety, Etiquette & Preparation

Mountain biking at elevation requires preparation. Here’s how to stay safe and ride respectfully:

  • Wear a helmet at all times. Full-face helmets and pads recommended for bike park or technical rides.

  • Yield properly — uphill riders and hikers have the right of way.

  • Respect wildlife — give animals plenty of space.

  • Don’t ride muddy trails — it damages the tread.

  • Pack essentials: multitool, spare tube, CO₂ or pump, snacks, and a small first-aid kit.

  • Hydrate and acclimate: The area’s elevation (8,000–10,000 feet) can affect performance.


Trail Etiquette

  1. Leave no trace. Pack out all trash.

  2. Stay on marked trails. Avoid shortcutting switchbacks.

  3. Ride in control. Be courteous to other riders and hikers.
