Velopedia analysis
What the specifications mean
The electric-assist system adds another maintenance layer, especially battery condition, charger compatibility, motor operation and any available diagnostic history. The 327% cassette range describes the available gearing more clearly than the component-group name alone. On the alloy frame, dents and hairline cracks around welds matter more than cosmetic scratches. Pay closest attention near the head tube, bottom bracket shell, dropouts and other heavily loaded junctions.
E-bike system
Electric-assist
The drive system needs its own battery, charger, motor-control and diagnostic checks in addition to the bicycle components.
Gearing
327% cassette range
Calculated from the published 11–36-tooth sprocket span.
Frame material
Aluminum / alloy
Dents and cracking around welds at the head tube, bottom bracket shell and dropouts deserve attention.
Wheel standard
700C · 622 mm
The label fixes rim diameter, not tire width or available frame and fork clearance.
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 →- FrameLook closely for dents and hairline cracks around welds, the head tube and bottom-bracket area. Cosmetic scratches matter less than a change in shape or a crack line.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 →
- 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
X-Small geometry
Riding position
At 394 mm of reach and 510 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 68.5° head angle combined with a 1056 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.
Small geometry
Riding position
At 406 mm of reach and 538 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 68.5° head angle combined with a 1078 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 424 mm of reach and 575 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 68.5° head angle combined with a 1111 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
The 438 mm reach and 613 mm stack sit in a moderate proportion, without a strong long-and-low or tall-and-short bias.
Handling tendencies
A 68.5° head angle combined with a 1140 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
The 451 mm reach and 650 mm stack sit in a moderate proportion, without a strong long-and-low or tall-and-short bias.
Handling tendencies
A 68.5° head angle combined with a 1168 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 X-Small to X-Large, reach grows by 57 mm and stack by 140 mm, showing how the frame becomes both longer and taller through the published size range. The rear center stays essentially constant at about 440 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.
