What the specifications mean
The fork provides the documented suspension, so fork setup and rear-tire pressure are the main adjustments for balancing the two ends of the bike. The electric-assist system adds another maintenance layer, especially battery condition, charger compatibility, motor operation and any available diagnostic history. Both 27.5- and 29-inch wheels appear in the record, but it does not establish a mixed front/rear build; confirm the correct diameter for the selected frame size.
Used-bike inspection
If you’re buying this bike used
Before any test ride: both brakes should stop the bike firmly and release cleanly; both wheels should run true and be securely attached; tires should have no casing damage; and the headset, handlebar, stem, cranks and pedals should have no looseness or play.
Follow the full used-bike inspection order →- FrameInspect the frame in bright light, especially around the head tube, bottom bracket, chainstays and clamped areas. Look for cracks, ripples, crushed sections or signs of a previous impact.Inspect the frame and fork →
- BrakesTest each brake separately and confirm it stops firmly and releases cleanly. Inspect the pads and braking surfaces for wear or contamination, and check the cables or hoses for damage.Inspect the brakes →
- E-bike systemConfirm the main battery charges with the correct charger, locks securely into its mount and has no case damage, swelling, corrosion or overheating marks. Power the bike on from cold, test every assist mode and ask for available battery-health and diagnostic records.Check the battery and electronics →
- SuspensionAsk when the fork was last serviced. Check the stanchions for damage, look for oil at the seals and make sure the fork moves smoothly without bushing play.Evaluate the suspension →
- Wheels & tiresSpin both wheels and watch the rims for side-to-side or vertical movement. Check for dents, cracks, loose or uneven spokes and hub play, then inspect both tire casings for cuts, cracking or exposed threads.Check wheels and tires →

Geometry interpretation
What this geometry means
Small geometry
Riding position
At 466.3 mm of reach and 628.4 mm of stack, the frame is longer relative to its height, which generally creates more potential for a stretched, lower-front-end position.
Handling tendencies
A 63.4° head angle combined with a 1260.5 mm wheelbase points to more stability-oriented steering and chassis behavior. The longer the chassis and slacker the front end, the more the bike tends to favor composure over very quick direction changes.
Medium geometry
Riding position
At 487.4 mm of reach and 632.8 mm of stack, the frame is longer relative to its height, which generally creates more potential for a stretched, lower-front-end position.
Handling tendencies
A 63.4° head angle combined with a 1283.8 mm wheelbase points to more stability-oriented steering and chassis behavior. The longer the chassis and slacker the front end, the more the bike tends to favor composure over very quick direction changes.
Large geometry
Riding position
At 507.3 mm of reach and 641.8 mm of stack, the frame is longer relative to its height, which generally creates more potential for a stretched, lower-front-end position.
Handling tendencies
A 63.4° head angle combined with a 1308.2 mm wheelbase points to more stability-oriented steering and chassis behavior. The longer the chassis and slacker the front end, the more the bike tends to favor composure over very quick direction changes.
X-Large geometry
Riding position
At 527.3 mm of reach and 650.7 mm of stack, the frame is longer relative to its height, which generally creates more potential for a stretched, lower-front-end position.
Handling tendencies
A 63.4° head angle combined with a 1332.7 mm wheelbase points to more stability-oriented steering and chassis behavior. The longer the chassis and slacker the front end, the more the bike tends to favor composure over very quick direction changes.
Across the size range
From Small to X-Large, reach grows by 61 mm and stack by 22.3 mm, showing how the frame becomes both longer and taller through the published size range. The rear center stays essentially constant at about 444.1 mm across sizes, so most of the wheelbase growth happens in the front half of the bike rather than by lengthening the rear triangle.
Geometry describes frame proportions and likely tendencies, not a ride test. Rider proportions, cockpit setup, tires, suspension settings, wheel configuration, and component choices can materially change how a bicycle fits and feels.
