SKU: N/A Categories: , ,

With a shorter shock stroke the eOne Forty 500 has a reduced rear travel by 133mm, creating a steeper seat angle. The shorter 140mm fork extends the reach and delivers a slightly steeper head angle. In combination these small changes make the eOne-Forty more agile and playful, a highly competent climber and perfect for all day trail riding.

All Merida 2021 eOne-Forty models use the powerful new Shimano EP8 85NM motor and bigger 630NM battery (with the exception of S frame sizes). The eOne-Forty 500 has Marzocchi Z2 suspension forks and a Shimano Deore 11-speed drivetrain.

Shimano EP8: The 2021 eOne-Forty Comes equipped with the new EP8 motor from Shimano STePS. It offers an increased performance of 85 Nm, less weight, a further reduction in size and less friction. On top of that, the new internal battery offers an extended range and super-fast charging capabilities.

Internal Block: First introduced in 2015, the e-bike version of the ‘Internal Block’ is incorporated directly into the frame and prevents the fork crown from hitting the frame in case of a crash or an extreme steering angle. As an extra protection, there are additional rubber bumpers on the frame to avoid any frame damage from the fork crown.

Clever Whel Size: To give the e-full suspension bikes precise steering, fantastic ‘rolling over obstacles’ behaviour yet maximum traction, Merida have combined a 29er front wheel with a 2.5″ tyre and a 650B rear wheel, equipped with a slightly wider tread 2.5″ tyre. The perfect combination of precision, playfulness and traction.

Thermo Gate: Specifically located openings on the carbon models near the head tube which work like a chimney and allow the warm air to dissipate to guarantee the optimum operating temperature of the internal battery. The ‘Thermo Gate’ enables the battery to perform at its best, in any condition.

Water Bottle Mounts: With the integrated battery, Merida were able to offer water bottle cage fixing points, allowing bottles or accessories like a lock or pump to the frame to be fitted into the main frame triangle. Great if you want to keep your back free of hydration packs and backpacks.
