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

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 Frog City 53 is the ultimate urban bike for 5-7 year olds. Designed for daily use, Frog's City bike allows children to commute to school or simply cruise the city in comfort and style. This versatile bike provides an upright ergonomic seating position, easy to mount step-through frame, 8-speed derailleur gears, a floating chain glider, full-length mudguards, a kickstand and a pannier rack, so riders are fully equipped for the city.

  • Lightweight sturdy aluminium frame - for easy handling around town
  • City/Step-through design - for ease of mounting and dismounting
  • Junior Tektro brakes - with small, easy to reach brake levers allowing for better control and improved confidence for Junior riders
  • Patented Frog cranks - reduces the distance between the pedals which increases efficiency and comfort and makes pedalling easier
  • Derailleur gear - the FrogFitTechnology® youth-specific 8-speed gear shifters provides more range so riders can effortlessly find the appropriate gear
  • Low-resistance Kenda City Tyres - very durable and ideal for travelling on varying terrains throughout the city
  • Floating chain glider - for added safety and easy to remove for maintenance
  • Low bottom bracket - for a more ergonomic seating position and better stability
  • Adjustable handlebar height - to allow handlebars to be lowered or raised within a range of 40mm, to suit child’s height
  • Accessories as standard - Reflectors, mudguard, pannier rack & kickstand included
  • Free 5 year warranty - on frame and forks
  • Swept handlebars & step-through frame
  • Please Note: We do not fit the mudguards when building the bike, they will need to be fitted by you at home. This is to prevent damage during shipping. Thanks.

With its slightly swept handlebars and longer head tube, the design allows for a more upright, leisurely riding position. And the lightweight step-through aluminium frame allows for smooth mounting and dismounting making the bike easy to ride and manoeuvre through the streets.

Derailleur gears: The Frog City bike features FrogFit Technology® youth-specific 8-speed gear shifters, which are best suited for moderate speeds and hills, perfect for efficient city riding. As opposed to hub gears, the derailleur gears provide more range so riders can effortlessly find the appropriate gear and they are easier to maintain.

Floating Chainglider: The floating chainglider, designed and manufactured in collaboration with Hebie, prevents clothing from getting stuck and the chain from getting soiled. And, it can be easily removed for cleaning and maintenance, without the need for tools.

Pannier Rack: The rear pannier rack is included as standard and can hold up to 25kg. A great way to transport bags and equipment when out and about in the City.

Kickstand: Frog's bespoke kickstand makes it easy to park the bike when taking a break or when loading the pannier rack. And is simple to fold away when no longer in use. Included as standard.

Please note: Light regulations change per country. We recommend contacting your local Frog Bikes stockist for more information and to ensure that your Frog bike adheres to local regulations.
