Kids move fast and grow faster. At times it can seem like there’s a small window for the perfect bike fit. The right bike for a young rider is a delicate balance between too small too big and a short-lived just right. If we’re going to inspire the next generation of riders we need to keep kids comfortably riding longer. The Jett is designed so that you’ll never fear the growth spurts. We did our homework to understand how kids grow—spoiler alert kids’ arms and legs grow more rapidly than their torso. We took to the books and designed a bike with child-specific touch points that withstand the development of young riders. The Jett is uniquely adjustable perfectly proportional and child-liftable—they’ll always be set to Jett. The Jett Multispeed features an adjustable handlebar that allows kids to fine tune reach as their arms grow. The 2-hole position cranks combined with longer seat tubes give plenty of flexibility to dial-in the optimal pedaling position. And whats more we designed the frame and reviewed every component to make the Jett one of the lightest bikes on the market. You’re going to have to beg them to get off this bike. We designed the Jett Multispeed to be uniquely adjustable with 2-hole position cranks adjustable handlebars and longer seatposts so kids can dial-in the perfect riding position as they grow. Every detail of the Jett Multispeed—including the 130mm Bridge saddle narrower-diameter grips and short-reach tool-less adjustable brake levers—was informed by Retül data from a kids’ research group to be perfectly proportional for young riders. A lightweight bike is simply more fun and the Jett Multispeed’s all-new A1 aluminum frame alloy fork Pathfinder tires and 8-speed drivetrain make it one of the lightest kids’ bikes on the market.

The Six Pack Mk4 now comes with an even wider beam pattern, it reaches far and wide down the trail whilst also enveloping the wheel to give total perspective. Shredding at high speed or tackling the most technical rock garden, is made even easier with an increased 5250 lumen measured output. REFLEX++ Technology ensures the right lumen output no matter the terrain, speed, or ride, combined with OMS to give runtime flexibility of 2 36 hours. Perfect for Enduro or Endurance.Reflex+ Technology - Reflex automatically adjusts the light to provide boosted output when riding hard and fast then intuitively dimming for the slower sections such as climbs. This is all to optimise battery capacity, to provide extra light when needed and save it when not required.Reflex achieves this by using data from 3D digital accelerometers including gyroscope and thermistors. It continually analyses the data to make seamless adjustments to benefit the rider, probably better than the rider can. In reality it is a form of artificial intelligence. The selected run time will be achieved by averaging the output over the period.Smart Port+ Technology - Smart Port+ enables the charge port to accept auxiliary accessories such as rear lights, remote switches, Support Cells and use your light as a power bank to charge USB devices.OLED Status Display - OSD - An LED display panel that gives clear information on which mode the light is in, runtime remaining in hours and minutes, percentage charged and feedback information during OMS. Patent Protected.Optimised Mode Selector - Various programs in the lights can easily be selected to offer a choice of run times and modes so you can find the right one for your ride, be it an all-night adventure or an intense blast.Intelligent Thermal Management - Patented circuitry within the light will reduce power to the LEDs, if they go beyond the optimum temperature, keeping the light as efficient as possible to maximise output and battery capacity. Once the light has cooled, the power is automatically restored.In the box: Six Pack MK12 GMB, QR Handlebar Bracket (31.8mm - 35.0mm), Fast Charger, QS Guide.Specification:LEDs: 6 x White XPL2(W3)IP Rating: IP65Max Lumens: 3750 (Reflex 5250)Battery: 17,000 mAh Li-IonRuntime: 2 - 36 HoursCharging Time: 8 HoursWeight: 386gMaterial: Anodised 6063 AluminiumLength: 118mmHead Diameter: 61mm
