Frame

Aluminum Superlite, Agile Ride Geometry, Boost 148, UDH™, Integrated Battery, Advanced Internal Cable Routing, Kickstand/Fender/Carrier Mounting Points, Advanced Internal Cable Routing, Gear and brake cables need a way to get from handlebar controls to frame – but what if there was no need for holes near the head tube? We came up with a design that takes cables into the frame via the headset, maintaining full internal cable routing but making it even neater and less obtrusive. Fixed Integrated Battery, Bosch SX technology incorporates a new, lighter and more configurable battery setup. To make the most of the weight saving, we've integrated the new battery fully into the down tube. This means we can position it optimally for the best weight distribution and handling, as well as saving more weight by building a down tube that's precisely the right size to fit, and without the need for an access hatch. And the Power More option means you can add an additional 250Wh battery quickly and simply, for extra range. It's the best of both worlds. Agile Ride Geometry, For off-road riding you need a bike that responds quickly, but also feels stable and secure. That's where Agile Ride Geometry comes in. Offering an ideal blend of on-demand steering precision, climbing agility and descending stability, it's perfect for every rider who values their time on the trail. If you're a mountain biker, you'll instantly feel at home... Smooth Welding, Smooth Welding isn't easy, but worthwhile things usually aren't. It has two advantages. First, and most obviously, it looks great: one tube seems to almost flow into the other. Second, and at least as importantly, it helps to minimise load peaks on welded areas for better frame strength and durability. Aluminium Superlite, CUBE's Aluminium Superlite starts with heat-treated 6061 aluminium, which has the qualities – high fatigue resistance, good stiffness, low weight and excellent strength – that are important for a bicycle frame. Then we make it into double butted tubes, to reduce weight without sacrificing any of its strength. The result? Exceptionally light, strong and tough frames. Not identified

Technical analysis

2 measures

How these figures sit among bicycles of the same class and model year. Context, not a ranking.

Lowest gear

18.2 gear inches

This value is within the central range for this class.

Cohort: Youth / General youth Model year: 2027
Sample: 52 bicycles with this information
Coverage: 80.0% of the class

Highest gear

Gearing

Estimated speeds at 80 rpm

Lowest gear: 7.0 km/h
Highest gear: 31.8 km/h

Total gear range 455%

Technical details and class reference

These speeds describe the gearing at the selected cadence, not how fast you can ride.
Calculated from published gear-inch values and their wheel-size assumptions.
These gearing values describe the bicycle, not a selected frame size.
A 100% range means one ratio; 500% means the highest ratio is five times the lowest.
For e-bikes, motor assistance cutoff is not represented.

Gear-inch range

Lower gear-inch values travel less distance per pedal revolution; higher values travel farther.

This bicycle: 18.2–82.9 gear inches
Class reference (p10–p90): 16.5–78.0 gear inches; The band runs from p10 for the lowest gear to p90 for the highest gear.
