Doona Liki S3 Trike

The Doona Liki Trike S3 Premium is the sweet-spot version of the world's most compact folding push trike for toddlers — more than the base model, without paying for extras you may not need. Shoulder pads, padded armrests, a storage bag, and pedal straps are all included, wrapped around the same patented fold that collapses to carry-on size in seconds and grows with your child from 10 months to age 3.

Why Parents Choose the S3

• Padded and protected from day one — shoulder pads cushion the harness straps and padded armrests give your toddler a comfortable place to rest; meaningful upgrades from the S1 that you'll notice on every ride
• 4 stages, one trike, no repurchasing — parent-controlled push mode (10–18M), street-facing push mode (18–24M), pedal tricycle (24–30M), and independent bike mode (30–36M); rated for children up to 37.5 lbs
• Storage bag included — dedicated storage bag clips to the trike for carrying snacks, a spare diaper, or sunscreen; keeps essentials within reach without a separate bag on your shoulder
• Pedal straps keep little feet in place — secure your toddler's feet to the pedals in tricycle and bike mode so they stay engaged and in control as they learn to ride independently
• Folds to 12.5 × 23.6 × 9.1 inches at the click of a button — fits in most airline overhead bins and every car trunk; the smallest folding trike on the market; fully assembled out of the box
• Parent steers, child explores — dual steering system lets you control direction from the adjustable parent handle in push mode while your toddler grips the handlebars; pedal lock keeps them safe while you're in control
• 14.7 lbs with a UPF sun canopy — lighter than most umbrella strollers; high-durability soft-ride wheels handle sidewalks, parks, and gravel; canopy folds flat when not needed; 1-year warranty included

The S3 is the right call if you want the comfort upgrades without the full S5 package — everything your toddler needs for years of rides, nothing you don’t.

Frequently Asked Questions

What is the difference between the Doona Liki Trike S1, S3, and S5?

All three share the same trike frame, UPF canopy, 5-point harness, parent control bar, and patented compact fold. The S3 Premium adds shoulder pads, padded armrests, a storage bag, and pedal straps over the base S1. The S5 Deluxe goes further with wooden handlebars, a cup holder, and a premium travel bag. The Midnight Edition matches the S5 in accessories and adds a blacked-out aesthetic with diamond-stitch seat and faux leather details.

Are the pedal straps on the S3 necessary, or can my toddler ride without them?

In parent mode and push mode (10–24M), pedal straps aren't in use — the pedals are locked and your toddler rests their feet on the footrest. Once your child transitions to tricycle mode (24–30M), the straps help keep their feet on the pedals as they learn to push and steer. They're not required, but most parents find them useful during the learning phase. They attach and detach easily.

Can I add a travel bag or cup holder to the S3 later?

Yes. Doona sells accessories separately, including a travel bag and cup holder, that are compatible with all Liki Trike models. If you travel frequently and want that protection for overhead bins, you can add the travel bag later. If you know from the start that travel is a priority, the S5 with the travel bag already included may be the more economical choice upfront.
