Overview
The Merida eBIG NINE 775 is a powerful commuter bike designed for urban travel, offering strong motor support and impressive hill climbing ability thanks to its high torque and 600W motor. Its 750Wh battery provides a decent range for daily commutes, and the removable battery adds convenience for charging and storage. While the bike feels lively and responsive, its braking confidence is limited, and the charging time is notably slow compared to similar models. The aluminium frame keeps it relatively lightweight, though it doesn't fold, so storage may require some planning.

Where to buy
Priced at £4,350, the Merida eBIG NINE 775 sits towards the higher end of the commuter e-bike market for 2024 models. It offers strong performance and build quality, but the price may be a consideration against similarly spec'd rivals.
Compared with similar commuter bike e-bikes on Bikkerr, this model sits £1,045.14 above average
The Merida eBIG NINE 775 is listed at £4,350, which sits at the higher end of the price spectrum when compared with similar commuter e-bikes from 2024. It offers a strong case for value with its competitive range of 70 miles, a robust 750Wh battery, and a powerful 85Nm torque that supports hill climbing and daily use effectively. However, buyers should consider that this price is notably higher than many alternatives in the same category, and similar e-bikes may offer comparable or better features at a lower cost. For a commuter e-bike, the balance of range, battery capacity and payload makes it appealing for those prioritising reliability and performance over cost, but the trade-off is that there are more affordable options with similar practicality. Riders who value a well-equipped, durable commuter bike with strong motor support and a good range may find the price justified, but those looking for a more budget-friendly option might find better value elsewhere.

This commuter e-bike offers a strong and responsive motor assistance that should feel lively and supportive for daily riding, with good punch from the motor and strong torque to help with hills and stop-start city conditions. Next to similar e-bikes, the motor support and torque should feel competitive, with the power-to-weight balance helping the assistance feel more immediate and natural. The torque sensor should make the power delivery feel more proportional to rider effort, offering a smooth and predictable ride, especially in urban environments. The motor setup is likely to suit riders who want a confident, punchy assist for commuting, with the trade-off being that the battery efficiency and range-to-weight balance may not be as optimized as some other models in the category.
This explanation is based on the bike’s motor power, torque, battery capacity, claimed range, charging
time, sensor type and how those figures compare with similar e-bikes in our database.
eBike FAQs
Is this bike suitable for daily commuting in the city?
The Merida eBIG NINE 775 is well-suited for daily city commuting, thanks to its strong motor support, high torque for hills, and a 70-mile range that should cover most daily trips. The removable battery adds convenience for charging, and the lightweight frame makes it easier to handle. However, the braking confidence is limited, so you may want to ride cautiously in busy areas, and the charging time is slower than average, which could be a consideration if you need to recharge frequently.
How does the motor perform when climbing hills?
The Merida eBIG NINE 775 handles hills well, thanks to its high torque and 600W motor, which provide strong support when climbing. You should expect the motor to assist effectively on moderate inclines, making it a solid choice for urban commutes with some elevation. However, very steep hills may require more effort, especially if you're carrying extra weight or riding in challenging conditions.
Is the battery capacity enough for a full day of riding?
The 750Wh battery should provide enough range for most daily commutes, especially in a city or suburban setting. With a range of up to 70 miles on a single charge, it's well-suited for longer trips or multiple stops. However, if you're planning to ride extensively throughout the day or in hilly areas, you may need to plan for additional charging stops, as the battery efficiency is average for this type of e-bike.
How practical is this bike for storage at home or work?
The Merida eBIG NINE 775 is a commuter bike, so it's designed for practical use in urban environments, but storage at home or work may require some planning. The bike doesn't fold, so you'll need a dedicated space that can accommodate its size and weight of 23.3 kg. However, the removable battery adds flexibility, as you can take it off for charging or storage if needed. If you have a garage, shed, or office with enough room, it should work well for daily use.
Does the bike feel comfortable on rough or uneven roads?
The Merida eBIG NINE 775 is built for urban commuting, and while it handles smooth roads well, its performance on rough or uneven surfaces may feel less refined. The rigid frame and lack of suspension mean it transmits more road vibrations to the rider, which could affect comfort over long distances or on bumpy paths. However, its lightweight design and responsive motor make it manageable for everyday use, even on slightly uneven terrain.
How long does it take to charge the battery?
The Merida eBIG NINE 775 takes longer than average to charge its 750Wh battery, which may be a consideration if you need to recharge it frequently. While the removable battery offers convenience for charging away from home, the slower charging time could mean planning ahead for longer commutes or multiple rides in a day. It's a trade-off for the high capacity and strong motor support the bike provides.
Is this bike good value for the price compared to similar models?
The Merida eBIG NINE 775 offers strong performance for the price, especially with its high motor power, torque, and large battery capacity, which make it well-suited for daily commutes and hill climbing. While the charging time is slower than average and braking confidence is limited, the bike's value is supported by its powerful assistance, good range, and removable battery, which adds convenience. It should be a solid choice for city or suburban riders who prioritize motor strength and battery capacity over fast charging or advanced braking systems.
What are the main limitations or trade-offs of this bike?
The Merida eBIG NINE 775 has a few trade-offs to consider. While its powerful motor and high torque make it great for hills and acceleration, the braking confidence is limited, which could be a concern when riding at higher speeds or in busy urban areas. The battery charges relatively slowly compared to similar models, so planning around charging time is important. Additionally, the bike doesn’t fold, which may make storage less convenient for those with limited space at home or work.

Getting the work/life balance right can be tricky, but the eBIG.NINE 775 manages it perfectly. It's ready to rip the trails at the weekend, with the off-road tyres, suspension fork, wide range drivetrain and updated Shimano EP801 motor helping you make short work of the climbs and descents. When it's time to get back to business, it's the perfect commuting partner, with a sleekly integrated 750 Wh battery delivering plenty of range and the ability to cross town without breaking a sweat. Arguably the most versatile e-bike in our range, the tried and tested eBIG.NINE embodies the perfect balance of day-to-day usability and sporty leisure activity. It's a bike that can handle serious off-road riding but can also handle the commute to work with ease - especially if you want to have some fun on the way. The high-quality aluminium frame integrates a choice of 630 or 750 Wh battery sleekly into the downtube, with a more economical frame featuring semi-integrated 504 Wh battery on some models. All feature powerful and smooth Shimano drive units that will power you up any hill. Ready to be equipped with mudguards and even a side stand (or available as the EQ fully equipped version), the eBIG.NINE will help you make the most of any situation.
