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 is the official technical partner of multiple World Tour and downhill 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.
