Merida is a huge brand that usually offers good-value bikes – the eBig Nine is no exception. It’s versatile: most at home on trails or a long commute, but it’s not out of place in the city (though it’s not as convenient as a step-through design).

It uses a STEPS 7000 motor with lots of power and torque – it’s the most refined Shimano motor we’ve tried. The “trail” mode in particular responds brilliantly to rider input up to its 32km/h limit.

The eBig Nine is efficient to pedal, with a comfortable riding position. It’s a fun bike to ride, with lively but balanced handling that creates confidence on all surfaces.

The Merida comes with a very good suspension fork and its wide-range 10-speed gears were appreciated by our testers. While it has full mudguards and a rear rack, there’s no chain guard fitted.

Overall, the eBig Nine is good value for a versatile “do-everything” bike.

How we test

Each e-bike was taken on a test route by two riders. The 5km route in and around Wellington’s CBD included city traffic, fast flat roads, hills, kerbs, wooden bridges and a busy waterfront path shared with pedestrians.

We also put the e-bikes through a gruelling 20km route around Wellington’s Wadestown and Northland suburbs. The main challenge was climbing a 2km-long hill five times at a steady 20km/h (a kilometre of vertical ascent) and descending the same twisty narrow road between climbs. It also included a short, steep section of rough path with a narrow barrier negotiated at walking pace, an undulating 5km of suburban streets, and a steep descent requiring brakes to keep the e-bike to the 50km/h speed limit.

Our riding tests, along with a static assessment of the features and functions of each e-bike, were used to score the performance of the motor system and the bike. Overall score includes:

Motor system (50% of overall score)

  • starting, stopping and responsiveness (40% of motor system score)
  • hill climbing assistance (30%)
  • controller and display (20%)
  • high-speed assistance (10%).

Bike (50% of overall score)

  • uphill and slow riding performance, ease of mounting and dismounting, off-bike handling (50% of bike score)
  • downhill and fast flat riding stability, safety and comfort (30%)
  • comfort and safety on bumpy and rough surfaces (20%).

Happy user


This Merida is our third electric bike and has proven entirely satisfactory. While mostly used around town, it's also covered the Tour Aotearoa route (carrying panniers) from Whanganui to Wellington - with a deviation by going right down to the south coast and around the track to get to Day's Bay.


The original motor was noisy and was replaced under warranty.

Recommend it?
