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 Nicasio 2 Gravel Bike 2026 blends durability, comfort, and performance for endurance riders tackling long commutes and mixed-surface miles. Built around a Series 2 double-butted CrMo steel frame and a full carbon fork, it delivers a smooth, efficient ride backed by precision Shimano GRX shifting and dependable hydraulic braking. With its thru-axle stiffness, tubeless-ready wheels, and all-weather versatility, it’s made for riders who demand reliability on every road.

Key Features and Benefits:

  • Series 2 Double-Butted CrMo Frame with Beyond Road Geometry: The steel frame provides a stable and compliant ride that absorbs vibration and flexes where needed. This results in lasting comfort and control over long distances and varied terrain.
  • Full Carbon Fork with 12mm Thru-Axle: The carbon construction reduces weight while improving front-end stiffness. The result is precise steering, responsive handling, and reduced fatigue on longer rides.
  • Shimano GRX RX400 2x10-Speed Drivetrain: Designed for mixed-surface riding, it delivers wide-range gearing and smooth shifts. This gives riders efficient power transfer and dependable performance across steep climbs and fast descents.
  • Shimano Hydraulic Disc Brakes with 160mm Rotors: The brakes provide strong, consistent stopping power in any weather. Riders gain control and confidence on wet, rough, or steep surfaces.
  • Vee Tire Co. Quickstyx 700x45 Tubeless-Ready Tyres: Wide and grippy, these tyres offer stability and comfort across tarmac and light gravel. They enhance traction and reduce punctures for more reliable all-season performance.
  • 12mm Thru-Axle Dropouts: These axles increase frame stiffness and wheel alignment accuracy. The result is a more solid, confident ride with improved handling and power delivery.

Built for riders who value endurance, reliability, and all-weather control, the Nicasio 2 brings together road speed and gravel-ready strength. Its steel frame and carbon fork work in harmony to provide comfort on long days, while GRX components ensure dependable performance with every shift and stop. This is a bike made for real-world riding—efficient, adaptable, and built to last.

The Marin Nicasio 2 Gravel Bike 2026 is ready to handle daily miles or weekend escapes with equal confidence. Choose it for a smooth, strong, and low-maintenance ride that performs wherever the road takes you.
