Yeti LTe T4

The Yeti LTe T4 is the flagship first-generation LTe for riders who want a full-power eMTB that stays composed when trails get steep, fast and properly rough. Its original UK RRP was £12,999, placing it firmly in ultra-premium territory. It is expensive. In return, you get the T4-specific Fox Podium Factory fork, SRAM XX Eagle AXS Transmission, Maven Ultimate brakes and DT Swiss carbon wheels around Yeti's 160 mm Sixfinity platform.

Why choose the flagship T4?

The LTe C2 and T3 share the same TURQ-carbon frame and Sixfinity suspension layout, so much of the bike's core character is available lower down the range. The T4 premium is for the finishing kit: the 170 mm Fox Podium Factory fork, XX wireless transmission, powerful Maven Ultimate brakes and HXC 1700 carbon wheels. That distinction matters. If you value those parts and want the top specification without piecing together upgrades, the T4 is the direct route; if the frame and suspension matter more than component tier, the C2 and T3 deserve serious consideration.

The current Yeti LTe T4 generation

The official MY26 LTe T4 XX AXS is part of the first-generation Bosch and Sixfinity LTe platform. It pairs a Bosch Performance Line CX-R drive unit with a removable PowerTube 800 Wh battery, Kiox 400C display and 4 A charger. The battery is removable. Published CX-R torque figures are not consistent, so the confirmed 750 W peak power and 800 Wh battery capacity are the clearer figures for comparing this bike.

A Medium tested by BikeRadar weighed 23.76 kg without pedals, which gives a useful sense of the T4's priorities. Low weight is not the mission here. The large battery supports long, climbing-heavy days, while the supplied charger takes approximately 6.9 hours to replenish a fully depleted battery. For shorter, lighter rides, a compatible 600 Wh PowerTube is an aftermarket option and saves a published 892 g, at the cost of capacity.

Sixfinity suspension and the way it rides

With 170 mm of front travel and 160 mm at the rear, the LTe T4 is happiest on demanding descents and technical climbs rather than flat, low-speed loops. Sixfinity offers 25%, 30% and 35% progression settings, letting you tune the rear end towards a more linear feel, a balanced setting or firmer end-stroke support. It is a useful choice. BikeRadar found the exact Medium T4 notably well balanced, combining grip and calmness on rough descents with enough pop to change direction.

The stock setup is a full 29er, with 29-inch wheels at both ends and clearance for tyres up to 2.6 inches. You can fit a compatible 27.5-inch rear wheel for extra rear clearance and quicker direction changes without intentionally changing the base geometry, but it needs the correct wheel-format chip position and a compatible Bosch rim magnet. The extra rear wheel and magnet are not supplied.

On broken climbs, the active rear suspension is designed to keep the tyre finding grip while the steep effective seat angle and 449 mm rear centre help keep your weight centred. The motor's strong overrun can take a little adapting to in very tight, slow manoeuvres. Give it time. On the way down, this is a planted, confidence-led eMTB that still responds when you pump a dip or unweight it over trail features.

Battery options, mud and workshop time

The 800 Wh battery is accessed through the downtube door. Medium, Large and X-Large frames can also take the optional 250 Wh Bosch PowerMore pack with the LTe mounting bracket and 200 mm cable, though it adds 1455 g. Small frames are not listed as PowerMore-compatible. Longer rides are still very much on the cards for Small-frame riders, but the stock battery is the capacity limit without that extender option.

Wet UK riding asks a bit more of a long-travel eMTB. Clean grit from around the protected linkage, battery door and cable ports, but avoid pressure-washing bearings and electrical seals. The Sixfinity layout has more pivots and bearings than a simpler suspension design, so regular servicing is part of owning this level of bike. Bosch diagnostics, firmware updates and a complete annual service also belong in the ownership plan.

The stock Albert rear tyre can struggle to clear persistent deep mud at slow climbing speeds, so a more open rear tread is a sensible winter swap when the original wears. Heavier or especially hard-charging riders may also prefer a tougher front tyre casing. One BikeRadar test bike developed a battery rattle caused by excess threadlock on a mounting bolt; any battery movement or rattle should be checked promptly rather than ridden on.

What changed from the Yeti 160E?

The LTe replaced the Yeti 160E platform. It keeps 160 mm of rear travel but moves from Shimano EP8 to Bosch CX and CX-R power, adds 5 mm of reach to every size and introduces the geometry-preserving mixed-wheel option. The result is a more flexible long-travel eMTB package for riders who want either a full 29-inch setup or a 29-inch front and 27.5-inch rear arrangement.
