AMS Hybrid One44 2026

The Cube AMS Hybrid One44 is a lightweight, carbon-framed, full-suspension trail bike built around the Bosch Performance Line SX motor — a 55 Nm, 250 W rated unit with a manufacturer-claimed peak of 600 W, housed in a 2.0 kg motor body. Paired with a 400 Wh integrated battery and 140 mm of travel front and rear on 29-inch wheels, it tips the scales from 16.2 kg (top SLT trim) to 18.7 kg depending on build. The community consensus is consistent: this is a bike you ride mostly without the motor, and that's the point.

Drive system and range

The Bosch SX produces strong torque for a mid-power, lightweight-category motor. At 55 Nm it punches above what the 2.0 kg weight might suggest, and the 600 W peak figure gives it meaningful punch on steep climbs. The trade-off is battery capacity: 400 Wh is modest by full-power standards, and the CompactTube 400 is integrated — not removable — so there is no bolt-on range extender option to compensate.

Real-world usage data from owners is unusually detailed here. @vls reported riding 75–78% of distance without any motor support across more than 1,700 km, with ECO accounting for nearly all assisted time and Turbo barely registering. A maximum single-charge range of 137 km was logged. The picture that emerges is of a bike where the motor acts as a climbing assistant rather than a constant presence — which suits riders who want trail feel over e-bike dependence, but will disappoint anyone expecting full-power endurance.

Geometry and handling

Cube offers eight size variants, though they come in four nominal sizes (S through XL) with two geometry expressions each. Reach runs from 428 mm at S to 501 mm at XL — a 73 mm spread that covers most riders properly. The head angle sits between 65.4° and 66.0° depending on size and configuration: not the slackest in the trail category, but appropriate for 140 mm travel and 29-inch wheels, offering a balance of climbing efficiency and descending stability.

Chainstay length is fixed at 450 mm across all sizes, and wheelbase scales from 1,193 mm (S) to 1,282 mm (XL). The consistent rear-centre figure keeps the handling character predictable across the range. The FSP 4-Link suspension layout is Cube's in-house design, aimed at pedalling efficiency — relevant on a bike where riders spend the majority of time unassisted.

Build and value

Ten trims span £3,799 to approximately £7,999, using either the C:62 or the higher-grade C:68X carbon frame. The entry-level C:62 Pro at £3,799 weighs 18.4 kg and comes with Fox 34 Float Rhythm suspension and Shimano XT brakes — a reasonable package. @derkoe flags it as a strong starting point for riders who want light weight without a premium outlay.

The C:68X SLX at £5,499 drops to 17.3 kg with Fox 34 Float Performance suspension, and @vls confirms the SLX trim as a genuine ownership sweet spot after nearly a year of riding. Step to the TM variants at £6,499 and you gain a Fox 36 fork and Fox Float X rear shock — more damper performance, though the C:68X TM weighs back up to 18.4 kg. The Super TM at £7,999 brings Fox 36 Factory Grip2 and SRAM Maven Ultimate, weighing 17.7 kg. The SLT trim at 16.2 kg is the weight flagship but pricing is not fully listed across all markets. @CalebDC notes the SLT's Transfer SL dropper "is something to get used to" — a mild caution on proprietary or unusual component choices at the top end.

Community-verified strengths

• Ride feel without assistance: @vls reports that riding without motor support feels the same as a regular bicycle — no perceptible additional drivetrain resistance from the Bosch SX system.
• Weight for the category: @GDAS notes it sits well under 20 kg; @derkoe highlights the 18 kg entry weight as a strong differentiator at the £3,799 price point.
• Long-term satisfaction: @vls reports no regrets after 1,700 km and close to a year of ownership across varied conditions.

Caveats and known gripes

• Motor noise: @vls reports a soft engine knock at 1,700 km, confirmed by a service centre as normal behaviour for Bosch SX units. @CalebDC acknowledges this as an unfortunate but documented characteristic.
