A surprisingly capable stock platform gives this ambitious Joyor build a strong foundation. The scooter arrives with dual 2,000-watt motors, a 60-volt battery, hydraulic brakes, adjustable handlebars, spring suspension, lighting and a large display, and the initial inspection is unusually thorough. Rather than immediately tearing everything apart, the creator demonstrates settings, acceleration, suspension behavior and component accessibility, establishing why the scooter seems attractive before attempting to transform it.
The complete teardown is where the project becomes more interesting than a conventional scooter review. Battery, controller, motors, swing arms, suspension, brakes, handlebars and wiring are methodically removed, revealing several practical design details along the way. Split-rim motors, reusable cable retainers, accessible connectors and the removable stem receive particular attention. The sheer length of the disassembly can become repetitive, but it provides useful context for viewers interested in how extensively the Joyor can be modified.
Cosmetic customization develops into its own trial-and-error project. An attempt to reproduce a mirror-like chrome finish with spray paint fails despite considerable experimentation, leading to a switch to chrome wrap over a dark paint job. Showing that failure rather than skipping directly to the successful solution makes the transformation more convincing, and the hand-cut reflective pattern gives the finished scooter a distinctive appearance. The process does run long, especially during sanding, wrapping and repeated fitting, but the visible progression helps justify the eventual result.
The mechanical modifications are dramatically more complicated. A larger 60-volt, 27-amp-hour battery is squeezed into the frame, while much larger motors require widening the swing-arm mounting arrangement with fabricated hardware. Tire clearance, suspension positioning and brake alignment then create additional problems, prompting custom brake adapters and repeated adjustments. These sections capture genuine problem-solving rather than presenting the conversion as a simple bolt-on upgrade, although some improvised structural solutions are demonstrated with limited discussion of engineering loads or long-term durability.
Clearance problems eventually expose one of the build's biggest compromises. The larger wheels interfere with the suspension, forcing substantial spring preload that leaves the suspension extremely stiff, while widened components also create steering-clearance problems with surrounding plastics. The creator acknowledges these shortcomings rather than pretending the conversion is flawless. More importantly, the combination of modified suspension geometry, fabricated mounting hardware and substantially increased performance makes the repeated emphasis on safety feel less comprehensive than the project itself demands.
The electrical conversion is similarly detailed, covering the VESC installation, motor and Hall-sensor connections, throttle and regenerative-braking setup, battery harness and controller configuration. That technical specificity is useful, but the eventual road test demonstrates why these settings cannot be treated casually. The scooter repeatedly shuts down when configured for 120 amps, which the creator attributes to demanding more current than the battery can handle; reducing the setting to 70 amps apparently stops the shutdowns. Because that diagnosis is presented from the build experience rather than supported by additional electrical testing here, it is best understood as the creator's explanation rather than a conclusively demonstrated cause.
Stock testing provides an especially useful reference point because the scooter reportedly reaches roughly 73 km/h during the run while retaining its original suspension characteristics. The modified version later reaches a displayed 81 km/h, but the creator explicitly describes the steering as loose and notes the absence of a steering damper while traveling at that speed. That moment gives the title's danger framing real substance: the additional performance is accompanied by instability, battery-related shutdowns and heavily compromised suspension rather than simply delivering an uncomplicated upgrade.
Pros
- The stock scooter receives meaningful inspection and road testing before modification, giving the build a useful performance baseline.
- Extensive disassembly reveals construction details, component accessibility and several customization-friendly design choices.
- Failed chrome painting, fitment problems and repeated mechanical revisions are shown rather than edited out of the project.
- The custom paint and reflective wrap produce a distinctive visual transformation with considerable hands-on work behind it.
- Motor, brake, battery and VESC installation provide substantial technical detail about the conversion process.
- Testing exposes real compromises, including power shutdowns, stiffened suspension and high-speed steering instability.
Cons
- The lengthy teardown, painting and repeated fitting sequences make the build considerably more drawn out than necessary in places.
- Major custom motor and suspension modifications rely on improvised fabricated hardware without much examination of structural loads or long-term durability.
- Solving tire clearance by heavily preloading the suspension sacrifices one of the stock scooter's most praised qualities.
- The explanation for the repeated electrical shutdowns is plausible within the creator's experience but is not independently demonstrated through deeper battery or electrical diagnostics.
- Reaching roughly 80 km/h with loose steering, no steering damper and heavily modified running gear introduces serious risks that deserve more sustained technical discussion.
The transformation succeeds as an entertaining engineering experiment precisely because so much goes wrong on the way to the finished machine. Its detailed fabrication, electrical work and candid troubleshooting make the project compelling, but the final combination of extreme speed, improvised hardware, compromised suspension and unstable steering also leaves important questions about whether the performance gains are worth the tradeoffs.
