TRETS: The junior trike with Wow Factor: The New TRETS Guarantees Big Fun for Little Riders.

The new TRETS from HASE BIKES is a trike for the youngest riders. To be exact: An infinitely adjustable trike for all kids between 3'3" and 5'3" in height (1-1.6m). The new TRETS has easy-to-use under-seat handlebars. They make young riders feel pretty cool with their “lowbars” - and honestly, they are!  For kids who prefer above-seat steering, like on a bike, optional “highbars” are also available – and give the new TRETS a classic “Easy Rider” look!

And now the wow factor: If the TRETS' poison-green finish wasn't eye-catching enough, there's also a set of funky stickers! Kids can choose between Wild Dinosaur or Pink "Glam." Neither is meant for girls or boys only - everyone should simply choose the stickers they like most!

TRETS is also ideal for children with neuromuscular disorders, such as cerebral palsy or muscular dystrophy, or with restricted movement, e.g. associated with spasticity, paraplegia, or dysmelia.  The TRETS even has a medical-aid number (in Germany)!

The TRETS also has features that parents will love:

Remove the front wheel, attach the draw bar, and the trike is in trailer mode. Then it can be hitched to one of the parents' bikes for long bike tours or for taking tired toddlers home from nursery school.  And last but not least: an optional rear-mounted Guide Bar is also available. Any parent could tell you why…

As a delta trike with a low center of gravity, the TRETS is extremely stable, which means that riders can get into the seat with no scary wobbling. The pedals with toe clips and straps, as well as elastic heel straps, guarantee good foot positioning and prevent slipping. The five-point harness keeps little ones in their seat – making the trike ideal for riders who are unable to hold themselves upright, for kids with the fidgets, and for anxious parents.

The TRETS can also be customized with a wide range of special accessories. For example, there are even Pendulum Pedals for children with severely limited mobility. Another ingenious option: The Crank Shortener is perfect for legs of different lengths or for when the knees cannot be fully extended.  And the TRETS can also be configured with “fixed wheel” drive for complete control when guiding a youngster (i.e. no freewheel).

Young trikers grow fast, but thanks to its modular design the new TRETS can grow with them: It’s adjustable for all kids between 3’3” and 5’3” in height (1–1.6 m).  For the stepless length adjustment, all you have to do is open a lever and slide the seat into the appropriate position. All without tools and without having to shorten the chain!  The new TRETS was developed with the aim of offering our youngest riders all the flexibility of the adult's TRIGO!
