Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

2025 Merida eBig Nine 400 Electric Mountain Bike - Grey/Black

Season:2025

Brand:Merida

Code:P855

The geometry of the Merida eBig Nine and eBig Seven bikes follow one very simple principle: As sporty as possible, as comfortable as necessary.

You ride to work in the morning but fancy a little off road detour on the way home? No problem ? that is what these bikes are made for!

Combining the best bits of a mountain bike and a trekking bike, these rugged machines can be fitted with mudguards and racks making them ideal for commuting or year round leisure riding.

The eBig Nine 400 is the cheapest Merida eBike to use Shimano's EP8 85Nm motor and 630w battery.

Many technical features and much of the thinking that went into the award winning eOne-Sixty make an appearance to deliver a stylish and well though through hardtail.

The strong, stiff aluminium frame is a result of extensive hydroforming, precision laser cutting and CNC machining. The battery is housed low down in the downtube behind a dual compound cover which deadens noise and can be charged in the bike using a satellite charging port.
