Bosch CX-powered 7020 aluminium enduro eMTB

The Nicolai GT1 EBOXX 2024 is a German hand-welded aluminium e-enduro built around the Bosch Performance Line CX Gen 4 motor, with a gravity-focused 180/170 mm travel split and uncompromising long-reach geometry. Headline numbers: 85 Nm of torque, 750 Wh battery, 180 mm front / 170 mm rear travel, a 64.25 degree head angle, sizes spanning 475 mm to 560 mm reach (S to XXL), and the Nicolai signature hand-welded chassis. There are no curated community quotes on file yet, so this verdict draws on the gold spec sheet and Nicolai/Bosch context.
Drive system and range. The Bosch Performance Line CX Gen 4 produces 85 Nm of torque and a strong manufacturer-claimed peak power output, with the eMTB mode delivering progressive, natural support that ramps with rider effort. The 750 Wh battery is generous for the gravity-focused chassis, providing four to five hours of full-power riding before reserves bite. Bosch dealer support is the strongest in the segment.
Geometry and handling. This is where the GT1 EBOXX is most distinct from rivals. The bike runs five sizes (S, M, L, XL, XXL) with reach starting at a generous 475 mm in size S and topping at 560 mm in XXL — these are exceptionally long numbers, more akin to motocross sizing than mainstream eMTB. The 64.25 degree head angle is fixed across all sizes, the 447 mm chainstay is shared, and wheelbase grows from 1,292 mm (S) to 1,385 mm (XXL). The geometry signals a bike built for tall and very tall riders who want a properly long-and-low gravity machine — Nicolai has long been the go-to brand for riders who find mainstream geometry too short.
Build and value. Only the base trim is on file in the gold facts, with the hand-welded aluminium chassis as the headline frame feature. Nicolai builds in Germany using TIG-welded aluminium with significant attention to weld quality, frame geometry adjustability and component compatibility. Pricing is not on file; expect Nicolai's positioning to be firmly at the premium end given the hand-built provenance and bespoke geometry programme.
Verdict. The Nicolai GT1 EBOXX 2024 suits buyers who specifically want a hand-welded German aluminium chassis, exceptionally long-reach gravity geometry (the size S already runs 475 mm reach, the XXL runs 560 mm), and the proven Bosch CX Gen 4 motor with 750 Wh battery. Less suitable for buyers seeking the most compact, agile handling, who should look at shorter-reach mainstream rivals with similar travel. Production status: current. Without published trim spec details or community feedback on file, direct dealer engagement and a demo on the bespoke geometry are essential before ordering.
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.
More planted than poppy — better on steep terrain than tight, fiddly singletrack.
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.
A workmanlike climber — expect to put in more rider effort on the steep stuff. 600W of peak power and 85Nm of torque — a strong full-power motor.
Rewards commitment; it should feel calmer as the speed rises.
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.
