Working & brainstorming stage. No final version confirmed. Spheno Shift is coming to Kickstarter soon.

The development notebook

On the
drawing board.

A current direction, with room to change. I’m working through fit, assembly and everyday use before confirming a product.

01 / The reason

One e-bike, different days.

I use my e-bike for daily commuting and gravel touring. Its handlebars are crowded, and overgrown countryside brings brambles close to my hands. Shift starts with a mount at the bar end and attachments for those different rides.

02 / The current design

A shared base. Separate attachments.

The current CAD explores a captive threaded collar with swappable pucks, a rounded mirror support and a broad handguard. A camera platform uses a standard ¼″-20 connection, with a bought adapter planned for compatible GoPro cameras. One attachment occupies each bar end.

The lowercase wordmark belongs on the rider’s left guard only. The two former lower-edge drainage holes have been removed from the current guard design.

03 / Fit comes first

Measure. Assemble. Revise.

The first PLA parts are for stationary fit and assembly checks on my Pedibal eCruiza’s stock handlebar. Bar dimensions, hand and brake clearance, full lever travel and easy hand withdrawal need physical confirmation. PLA fit prints are not qualified riding products.

The outer return is intended to help limit sideways hand slip. It is not a hand restraint or a guarantee against a fall. Strength, thorn resistance, retention, vibration and wear remain to be established.

04 / Surfaces & airflow

Make the evidence first.

Weave is a printed cosmetic surface, not carbon-fibre laminate. It has no demonstrated aerodynamic advantage. A Pro direction for mountain-bike racing will compare smooth and textured surfaces under matched conditions; no faster texture, drag reduction or race eligibility is confirmed.

The top-down gallery is a geometry view, not an airflow simulation or test result.

05 / A possible release

Print it. Or choose a physical kit.

I plan to explore both digital models and physical products, with standard off-the-shelf hardware. Materials, fit options, licensing, kit contents, prices and delivery dates will depend on what the prototype work establishes. More attachments are an intention, not a confirmed release schedule.

About the images

Design views,
clearly labelled.

The product galleries use renders of the current CAD. Grips, brake controls, cameras and adapters are illustrative references. The lifestyle scenes are AI-generated concepts, not photographs of a tested prototype.

Neither type of image proves fit, safety or performance. Actual product photography will follow a working physical assembly.
