Marin\u2019s all-new Alpine Trail E Bosch electric mountain bike use Bosch\u2019s full-power Performance Line CX motor and run a mixed wheel (29in front, 27.5in rear) setup as stock.<\/p>

Like its non-electric counterpart<\/a>, the Series Four aluminium frame is all-new, with travel boosted up to 160mm compared to the previous generation Shimano-powered Alpine Trail<\/a>.<\/p>

Moving from Marin\u2019s standard MultiTrac 2 linkage-driven single pivot suspension to the LT version, it now uses a Horst-link design.<\/p>

Flip chips<\/a> adjust bottom bracket height and chainstay length, while headset cups adjust the head angle between 62.4 degree and 64 degrees.<\/p>

At launch two models are available \u2013 the Alpine Trail E2 and E1. The top-spec E2 retails for \u00a36,385 \/ $6,599 \/ \u20ac7,249 \/ CAN$8,799 and the more affordable E1 costs \u00a35,515 \/ $5,699 \/ \u20ac6,299 \/ CAN$7,599.<\/p>

Head to our full review of the new Marine Alpine Trail E2<\/a> to hear how the bike performs on the trails<\/p><\/div><\/div>

The Alpine Trail E Bosch uses Marin\u2019s Series 4 aluminium with a chunky straight downtube and more svelte top tube and seat- and chainstays.<\/p>

Cables enter via rubber ports on the downtube, which are held in place using a small hex bolt. <\/p>

The ports\u2019 membrane is punctured to allow the cable to pass through. This forms a tight seal around the cable to reduce rattle and improve weatherproofing, according to Marin.<\/p>

The seat tube diameter is up from 30.99mm to 34.9mm. This is claimed to boost frame strength.<\/p>

There\u2019s plenty of chain slap protection. This is made from a fibreglass-infused nylon.<\/p>

The bike now uses SRAM\u2019s UDH standard<\/a>, so the bike is SRAM Transmission groupset compatible.<\/p>

Underside protection is also fitted. This clips and bolts in place, and needs to be removed to access the bike\u2019s battery. Drain ports let any moisture escape the frame\u2019s tubes.<\/p>

Headset cups are used to adjust the bike’s head angle. – Andy Lloyd \/ Marin Bikes<\/figcaption><\/figure>

Angle-adjusting headset cups are also included as standard. The upper cup offsets the fork\u2019s steerer tube at an angle relative to the head tube to adjust the bike\u2019s head angle.<\/p>

To make the head angle slacker, the cup offsets the fork\u2019s steerer to the rear of the headtube, and to make it steeper it does the opposite, offsetting it to the front of the headtube.<\/p>

The lower cup uses a nylon doughnut to accommodate the angle of the tube; when the headset is tightened the doughnut lets the bearing angle within the metal cup, mirroring the position of the upper headset cup.<\/p><\/div><\/div>

Suspension design<\/h3>

Moving to the brand\u2019s all-new MultiTrac 2 LT design sees a shift from the linkage-driven single pivot design to a Horst-link system. This comes with a corresponding increase in travel from 150mm to 160mm.<\/p>

According to Marin, moving the pivot from the seatstay to the chainstay provided designers more freedom to reduce anti-rise to improve suspension performance while braking. It also increases mid-stroke support and bottom-out resistance.<\/p>

Additionally, the new design helped Marin implement its adjustable chainstay flip chips.<\/p><\/div><\/div>

Motor and battery<\/h3>

Fitted with Bosch\u2019s 85Nm Performance Line CX motor, this offers up to 340 per cent assistance.<\/p>

The inbuilt top tube controller has Bosch\u2019s usual ten-stage battery and colour-coded mode indicators. It\u2019s paired with the wireless Mini Remote, fitted to the handlebars.<\/p>

A 750Wh Powertube battery powers the motor. This slides into the bike\u2019s full-circumference downtube via a port at the bottom bracket. The rail system \u2013 used on a lot of Bosch bikes \u2013 uses a single clip to keep the battery in place.<\/p><\/div><\/div><\/div><\/div>

The 2024 Alpine Trail E Bosch\u2019s geometry can be adjusted depending on rider needs and trail types.<\/p>

The head angle can be adjusted from its standard 63 degree position 0.75 degree in either direction.<\/p>
