Top of the first-generation Slash+ range, the Trek Slash+ 9.9 X0 AXS T-Type combines the TQ HPR50 motor, a 580 Wh battery, a RockShox ZEB Ultimate fork and a Vivid Ultimate shock, with 170 mm at both wheels. It weighs 20.88 kg in size M according to Trek and is offered here in XL. The Mercury colourway, a metallic silver grey, shows off the shapes of the carbon frame.

Who is it for?

For the experienced enduro rider who targets the steepest descents and wants race-bike spec, without the weight of a full-power e-MTB. The XL size suits riders from 188 to 195 cm.

The LVR workshop view

OCLV carbon that soaks up big hits. On an electric enduro bike, the frame has to cope with both the weight of the motor and the violence of landings. Trek therefore kept its OCLV Mountain carbon for the Slash+, laid up to withstand impacts, and added integrated protection under the down tube. This 9.9 pairs it with carbon rims that stiffen the whole bike without weighing it down: 20.88 kg in size M.

	Fuel EXe (TQ HPR50)	Slash+ (TQ HPR60)	Rail+ (Bosch CX)
Motor torque	50 Nm	50 Nm (HPR50) or 60 Nm (HPR60)	85 Nm, up to 100 Nm via the app
Battery	TQ 360 Wh	TQ 580 Wh	Bosch PowerTube 800 Wh
Weight (M)	18.68 to 19.33 kg	20.38 to 21.83 kg	23.73 to 25.08 kg
What it means	Feels close to a non-assisted mountain bike	Light enduro, more range	Full power, more weight

Put simply: the same frame and motor as the Slash+ 9.7 SLX/XT, but with RockShox Ultimate suspension, a wireless drivetrain and carbon wheels for the rider who wants the best build.

The ZEB Ultimate, with its 38 mm stanchions and Charger 3.1 damper, stays precise under hard braking on a broken-up slope; the Vivid Ultimate handles the heat of long descents without losing control. On the red earth of the Salagou, where grip changes from one corner to the next, this pairing helps you hold your line.

The X0 Eagle AXS T-Type drivetrain mounts directly to the UDH hanger and is operated without cables, like the Reverb AXS post: fewer housings in the frame, less maintenance. The TQ motor only assists pedalling up to 25 km/h, the European limit for 250 W rated, and can't be felt beyond that.

Which Slash+ should you choose?

Model	Motor / battery	Rear / front travel	Drivetrain	Weight (M)
Slash+ 9.7 SLX/XT	TQ HPR50 / 580 Wh	170 / 170 mm	Shimano SLX / XT 12-speed	20.38 kg
Slash+ 9.9 X0 AXS T-Type	TQ HPR50 / 580 Wh	170 / 170 mm	Wireless SRAM X0 AXS	20.88 kg
Slash+ 9.9	TQ HPR60 / 580 Wh	170 mm fork	Wireless SRAM X0 AXS	21.83 kg
Fuel+ LX 9.8 Eagle 90	TQ HPR60 / 580 Wh	160 / 170 mm	SRAM Eagle 90 12-speed	20.88 kg

Our take: compared with the Slash+ 9.7 SLX/XT (20.38 kg), this 9.9 X0 AXS adds 500 g in M despite its carbon wheels; what it mainly gains is suspension and wireless controls. The Fuel+ LX 9.8 Eagle 90 offers 160 / 170 mm and 60 Nm for the same weight.

Your questions

ZEB or Fox 38, what's the difference?	Two 38 mm enduro forks; here the ZEB Ultimate offers the most comprehensive compression adjustment.
Does the Reverb AXS post need charging?	Yes, it uses a removable SRAM AXS battery, supplied with its charger.
Can a chain guide be fitted?	The frame has an upper chain guide mount.
Is Mercury grey a gloss finish?	Yes, it is a metallic silver that plays with the light and stays easy to look after.

The LVR Cycles verdict
