Nicolai GT1 EBOXX 2023

The Nicolai GT1 EBOXX is the touring-flavoured all-mountain member of Nicolai's hand-welded German aluminium EBOXX line, built in 7020-T6 to order at the brand's factory in Mehle, Lower Saxony. The GT1 shares the EBOXX platform's 160mm of Horst-Link travel and 64.25-degree head angle with the enduro G1, but uses the Geolution Tour geometry: a raised, more upright front end for a comfortable, versatile position rather than the race-focused riding position of the G1. All builds run a Bosch Performance Line CX Smart System motor (85 Nm, 600 W peak) on a mullet 29/27.5 wheel setup across five sizes from S to XXL covering 1.55m to 2.10m riders.
For 2023 the GT1 EBOXX came in three builds. The QLF (from 8,999 EUR) is the derailleur model, running a SRAM GX Eagle 12-speed drivetrain, EXT e-Storia shock, Magura MT7 brakes and a RockShox Reverb AXS dropper on a 700 Wh PowerTube. The E14 (from 10,499 EUR) swaps the cassette for a Rohloff Speedhub E14 electronic 14-speed hub gear and Gates Carbon Drive belt, also on a 700 Wh pack. The newest 3x3 (from 10,499 EUR, marketed as the EWB) uses the EFFIGEAR-derived 3x3 NINE 9-speed grease-lubricated gear hub with a Gates belt, paired with a Fox 38 fork, Fox DHX coil shock and the larger 750 Wh battery, pitched as a lower-maintenance alternative to the Rohloff.
Common to all three is Nicolai's TIG-welded, fully machined construction, Fox 38 GRIP2 Factory fork, Hope Fortus wheels, Continental Der Baron tyres and SQlab finishing kit, plus a 5-year frame warranty and 10-year spare-parts guarantee. The optional Explorer Kit (mudguards, rack, lights) extends the bike to commuting and touring duty. At a claimed 27.2kg it is a heavy, deliberately over-built machine whose appeal rests on durability, hub-gear or belt-drive low maintenance and full customisation rather than light weight.
This 2023 GT1 EBOXX has since been discontinued and replaced by the current GT1 EBOXX NST, which carries the same Geolution Tour platform and Bosch CX drive with a Rohloff E14 belt-drive build.

Geometry read

What the numbers mean on the trail

Computed from this bike's geometry, spec and build kit — reach, wheelbase, chainstay, head and seat angles, travel, motor, weight and the fork/tyre/brake spec — and worked out per size, because a fixed chainstay can make an S and an XL feel very different.

Size

Descending

Slack 64.25° head angle, 160mm travel and a long 1336mm wheelbase — composed in the chunk, confident when it gets steep, and stable through fast corners.

Playfulness

More planted than poppy — better on steep terrain than tight, fiddly singletrack.

Size balance

Very front-long in L: 889mm front centre on 447mm stays (FC:RC 1.99). Rock-steady at speed, but you have to actively weight the front in flatter corners.

Technical climbing

Climbs well — a 77.9° seat keeps the front planted. 600W of peak power and 85Nm of torque — a strong full-power motor.

Best suited toFast, steep, rough tracks — and riders who want maximum composure.

Rewards commitment; it should feel calmer as the speed rises.

Watch out forL runs front-long (FC:RC 1.99).

A 889mm front centre on 447mm stays means taller riders must actively weight the front to keep it gripping. The chainstay stays 447mm on every size, so L feels more front-long than the smaller sizes.
