Height Extension Kit for 1693EL

The 1693EL Electric Repair Stand 2.0 raises the bike's clamp from 240 mm at the lowest setting to 1750 mm (~1.75 m) at the highest, which covers nearly every working-height preference a mechanic might have. For a 6′3″ or 6′5″ mechanic working on a tall cargo e-bike, that ceiling occasionally sits just below the comfortable working height for the cockpit; the bike could go up another 25 cm and the back would thank you. The 1693EL.11 Height Extension Kit is the bolt-on column extender that raises the stand's maximum height by an additional 250 mm.

The use case is narrow on purpose; most shops don't need it. The extension is the right buy in two specific configurations: tall mechanics whose neutral working height is above the stock 1.75 m ceiling, and shops servicing tall-cargo or extra-long-wheelbase e-bikes where the bottom-bracket-area sits at handlebar height on a stock stand.

V2 stand compatibility

The 1693EL.11 is the V2-only height extension kit. Per Unior corporate: “this kit is only compatible with the later revisions of the 1693EL that have an aluminum column. The first production run, with a steel column, is not compatible with this kit.” The V2 aluminum column accepts the extension geometry; the V1 steel column doesn't.

If you're not sure which generation your stand is, the visual tells: V2 has a smooth aluminum column with internal wiring (no external cable runs) and two USB ports (one A, one C) on the control panel. V1 has a textured-paint steel column with external cabling and no USB. Stands shipped to US shops after mid-2021 are typically V2.

What it does

The kit adds 250 mm to the stand's stroke ceiling, raising the maximum from 1750 mm to 2000 mm. The travel-limit memory, the load display, and the rest of the V2 control electronics work unchanged with the extension installed; the extension is mechanical column hardware, not an electronics upgrade.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The 1693EL.11 is the V2 column's ergonomic upgrade for the long install: 250 mm of additional working stroke that a shop can add years after the original purchase without retiring the stand. The aluminum column was designed to accept this kind of extension; the V1 steel column wasn't, which is why the kit's compatibility is generation-specific.

Pro tip from our mechanics

The honest test for the height extension is whether you currently lift the bike to within the last 50 mm of the stock 1.75 m ceiling on a regular working day. If yes, the extension is worth ordering; if no, the stock height is the right ceiling and the extension is parked accessory inventory. Tall mechanics tend to learn this within a week of installing the stand; tall-cargo specialists usually know before they uncrate it.
