The captive collar.
Turn the outer ring to engage or release the puck’s thread. Its inner lip is retained behind the head.
Spheno Shift / Coming to Kickstarter soon
Mirrors for the everyday.
Handguards for the unexplored.
Camera mounts for what comes next.

A clearer idea of what’s behind.

Coverage around your hand.
Actual design meshes. Grip and brake are illustrative. Fit on the stock Pedibal eCruiza handlebar is still to be confirmed.
Made for crowded e-bike handlebars
A display. Assistance controls. Gears. Brakes. Lights. A bell.
Your handlebars already have a lot going on.
Move the mounting point. Bar-end attachments free up clamp space around the controls, with a base that stays in place between swaps.
Coverage with an outer edge. The guard wraps around the end of the grip, with an outer return intended to help limit sideways hand slip.
Keep the hand free. Lateral support and control clearance still need physical testing. The guard must allow easy hand withdrawal; it cannot guarantee against a fall.
Every angle. Every detail.

01 / 05
The open side faces the rider. The shell curves ahead of the hand and around the bar end.
Sculpted coverage. A broad curved shell designed around the grip and brake controls.
A woven-look finish. Texture printed into polymer. This is not carbon-fibre laminate.
One shared base. The guard and mirror each attach through the same collar and puck interface.
Inside the shared mount
A simple threaded collar brings the two faces together.
The base stays in the handlebar.

Turn the outer ring to engage or release the puck’s thread. Its inner lip is retained behind the head.
The bar-mounted head provides the mating toothed face. Those teeth are designed to resist the attachment twisting.
Each attachment bolts to its keyed puck. The collar draws the puck into the head; unscrewing allows the attachment and puck to leave together.
Fasteners and the in-bar expander are omitted from this cutaway. The separated position explains removal; it is not a motion simulation. Preload, wear and vibration retention remain to be tested.
This is a design explanation, not riding instructions. There is no secondary latch or plunger in this revision. The production tightening procedure and checks will follow validation.
Same bike. Different day.
The reason it exists: an e-bike that does the daily commute and goes gravel touring.

THE HANDGUARD / GRAVEL TOURING
A new scene guided by the current CAD shell. Designed with encroaching vegetation in mind; coverage and thorn resistance still need physical testing.

THE MIRROR / DAILY COMMUTING
A rounded support and replaceable optical insert for the everyday journey.
AI-generated concept · Not a prototype photographThese generated scenes explain the intended use and photography direction. Geometry and reflections are illustrative. Actual product photographs will follow assembly and testing; these scenes are not evidence of performance or qualification.
Next attachments / In development
One short printed bracket.
Two standard camera connections.
¼″-20 UNC
A bought metal camera screw and a simple pad on a rounded platform. The same keyed puck and captive collar as the mirror and guard.
Explore the mount ↗GOPRO CONFIGURATION
Add a bought ¼″-20 tripod adapter for a compatible GoPro. Standard hardware keeps the part count low and provides the camera’s tilt adjustment.
See the development notes ↗D01 is a bench-fit concept. Camera model, screw depth, load limits and vibration retention still need checking. One attachment occupies each bar end: the camera replaces the mirror or guard on that side. An independent camera tether is planned. Camera and adapter shapes in the gallery are illustrative.
Two directions. One platform.
SURFACE OPTION
The signature woven-look printed surface. A visual and tactile choice for the everyday rider and gravel explorer.
Raised weave has no demonstrated aerodynamic advantage on this guard.
MOUNTAIN-BIKE RACING / DEVELOPMENT
A racing direction exploring surface treatments that could reduce drag while retaining useful hand coverage.
Smooth controls and texture samples are prepared for testing. Final texture, speed benefit and race eligibility are not yet established.
Airflow is part of the design brief. Top-down views here show geometry, not CFD. Pro will compare surfaces under the same conditions before any performance claim is made.
Planned Kickstarter rewards
Printable files, assembly guidance and a list of the standard hardware and mirror inserts to source separately.
A finished kit through the selected production process. Materials, fit options, contents and prices will follow validation.
Camera and GoPro configurations are the next attachments in development around the shared mount. Digital files and physical kits are planned for the Kickstarter campaign. Rewards, prices and delivery dates will be confirmed before launch; no orders are being taken here.
Where we are
Coming to Kickstarter soon. The campaign is in preparation; launch timing depends on prototype testing and Kickstarter review. No final version, specifications, materials, price or release date is confirmed. The first PLA parts are for stationary fit and assembly checks. A complete working assembly, riding retention, control clearance and aerodynamic performance still need verification.

A planned commitment / Across the shop
I plan to donate 10% of profits from sales across the spheno labs shop to an NHS charity.
The charity will be chosen later. I’ll name the beneficiary and publish the calculation before sales open.
