Built with care: Our mechanics fully assemble your bike before it's carefully packaged and shipped to you.

At Tweeks Cycles, we ensure your bike arrives fully assembled and, most importantly, well packaged so it arrives with you as it left us.

Upon delivery, simply unpack it, attach any included pedals (believe it or not, some bikes don’t come with pedals!), adjust the handlebars, and you're ready to ride!

It’s all super simple!

BUT! Please take extra care when fitting any pedals that are provided with your bike. Pedals are side specific and MUST be fitted to the correct side of the bike. They are usually clearly labelled Left and Right. Failure to do so will permanently damage the bike, void the bikes warranty and lead to many tantrums, for children or grown children alike!

Comprehensive 14-Point Inspection

Each bike undergoes a meticulous 14-point inspection to guarantee optimal condition and performance:

  • Ensure Cycle is free of any mechanical damage, paint chips or missing parts
  • Grease seat tube, secure seat clamp, make sure the saddle is level and ensure all fixings are secure
  • Ensure handlebar, stem and brake/gear levers are secured
  • Assess headset for play or tightness
  • Ensure handlebar tape or grips are fitted securely
  • Ensure wheel nuts, quick-release levers or through axles are tightened (please note: some adult mountain bikes come with the front wheel removed for transport), true the wheels for optimal alignment and check wheel bearings for proper adjustment
  • Inflate tyres to the correct pressure
  • Ensure front and rear brakes operate correctly. Bleed hydraulic brakes if required
  • Ensure pedal threads are greased
  • Test all gears to ensure smooth operation
  • Check suspension system for correct operation and ensure bolts are tight (if required)
  • Ensure smooth bottom bracket rotation with no free play and secure crank bolts
  • Check cable/house routing and that cable ends are fitted
  • Install reflectors and bell (to be done by customer)

This thorough process ensures your bike is in peak condition upon arrival. We do not fit mudguards or other accessories prior to shipping as these are likely to be damaged in transit.

Note on Electric Bikes

Due to shipping restrictions, in some circumstances you may receive your new electric bike and its battery separately. This is due to carriage restrictions on some removable batteries.

Note on Balance Bikes

Balance bikes are shipped unassembled, allowing you to enjoy the building experience and retain the original packaging-perfect for gifting.

Details

The Marin San Quentin 1 Hardtail Mountain Bike – 2026 blends robust construction with advanced components for dependable trail performance. Its Series 2 6061 aluminium frame combines strength with efficient weight distribution, while internal cable routing offers a clean, low-maintenance setup. A 130mm SR Suntour XCM34 suspension fork absorbs rough terrain, and tubeless-compatible wheels provide enhanced grip and puncture protection. This is a hardtail built for precision control, reliability, and adaptability across a variety of riding conditions.

Key Features and Benefits:

  • Series 2 6061 aluminium frame with double-butted tubing: Increases frame strength while keeping weight balanced for easier climbing and handling. This ensures lasting durability with reduced rider fatigue over longer distances.
  • Internal cable routing: Protects cables from dirt and debris for smoother shifting and braking. This reduces maintenance needs and improves long-term reliability.
  • SR Suntour XCM34 Boost suspension fork with 130mm travel: Improves front-end stability and impact absorption on uneven trails. This results in more precise steering and better control in technical sections.
  • Marin aluminium double-wall rims with 29mm inner width, tubeless-compatible: Supports wider tyres for improved traction and stability. This enhances cornering confidence and reduces the risk of flats.
  • Tektro M275 hydraulic disc brakes with 180mm rotors: Delivers consistent braking power in all conditions. This allows controlled stopping on steep descents and in wet weather.
  • microSHIFT 1x9 drivetrain with wide 11-46T cassette: Offers a broad gear range for tackling steep climbs and fast descents. This provides smooth, efficient power transfer with minimal mechanical complexity.

Built for riders seeking dependable trail performance, this bike focuses on control, stability, and low maintenance. The combination of a strong, lightweight frame, capable suspension, and reliable braking ensures consistent results across a range of terrains. The wide-gear drivetrain reduces strain on challenging climbs, while the tubeless-ready wheels and wide tyres deliver confident handling in varying conditions.

Experience the blend of strength, control, and low-maintenance design that makes this hardtail a practical choice for serious off-road use. Its durable build and rider-focused features make it a solid investment for consistent trail performance season after season.

* Bike Delivery Info

A bike has to go though a Pre Delivery Inspection (PDI Check) prior to despatch, ensuring the bike is thoroughly checked and set up prior to you receiving. This also means an express delivery service is unavailable. We strive to despatch bikes within 3-5 working days. Please note this may change over school holidays and the festive season (November/December). For more information on the process please visit our pre-build page.
