a basic electric mountain bike, but powerful

The dynamism of the E-Summit 740 makes it a very comfortable and malleable e-bike, but is it enough for city use?

The Nakamura E-Summit 740 was not designed only for the urban environment. If its racy and sporty look is a bit flashy in the middle of the city, it is an all-terrain electric-assisted bike that is easy to use, aesthetic and rather efficient.

We were able to test this model, sold by Intersport and available at € 1,599. Its price may decrease depending on the aid available for the purchase of a bicycle in your area. In Strasbourg, Nantes, Amiens or Ile-de-France, they can sometimes be combined with departmental aid and allow the price of this model to be lowered, for example, below € 1,000.

An ATV built around a homemade engine

Tested in urban and peri-urban areas, the bicycle shows good adaptability. Beyond the very sporty design, perhaps too much for central Paris, but acceptable in very close suburbs, the 27.5-inch tires offer excellent grip on any type of ground.

The Nakamura brand, developed by Intersport, has for many years participated in the democratization of mountain bikes and VAEs, it has a wide range of models assembled in France. The E-Summit 740 is no exception. It was assembled by the Manufacture Française du Cycle which produces all the bikes stamped Nakamura. The aluminum frame of this model is ultra strong and the brushed finish is quite elegant. This is one of the strengths of this mountain bike, which can give it an urban look; its neat design.

The mid-engine, a manufacturer’s house design named Naka E-Power Max, can develop a torque of 80 Newton meters (Nm), the average of VAE motors is between 40 and 80 Nm, which makes it a relatively powerful engine. On this model which requires raw power to face terrain traversed by mountain bikes, it is perfectly integrated and it is coupled to a battery nested in the frame of the bike.

One would almost doubt that this is an electrically assisted bicycle as the integrations have been so successful.

In terms of performance, the engine of this sports model is defending itself rather well. In rough terrain in town and in the countryside, its acceleration capacity allows you to get out of dangerous situations very quickly. It has 4 levels of electric assistance combined with the 9 speeds of the bike. Tested in the city, at 25km / h (30km / h with muscular effort), launched at maximum speed on a regular basis, the weight of the bike coupled with the impulse of the motor tend to cause slight jolts during movements, the time for the motor to take over. An advantage for climbing slopes and valleys since this acceleration capacity makes it much easier to climb. A disadvantage for the city however, since the behavior can confuse the first kilometers.

If the engine is rather efficient, the battery is not left out. It is rechargeable in just three hours. And at level 4, the highest level of electric assistance, we can certainly count on 50 to 70 km of autonomy. The first level and the second, more economical, allow the cycle to be pushed up to a hundred kilometers. The battery, guaranteed for 2 years, is easily removable using a small key. But, the E-Summit 740 can also be recharged directly from the mains.

In terms of driving comfort, the E-Summit 740 is impressive and allows for good cycling. The handlebars are 73 cm wide for a size M bike. The rider can then position his hands comfortably. This sporty cut gives confidence to the cyclist who does not hesitate to overcome my obstacles in his path. The 13 cm fork cushions rather well the potholes in the city, the embankments in the countryside and allows to cross with ease the wastelands and wastelands in peri-urban environment and this is what we ask of a mountain bike. accessible and easy to use.

An anti-theft system via an application

But its big weak point in the city, which is partly explained by its use mainly intended for rural or off-road areas, remains the anti-theft system. The E-Summit 740 is connected to your phone using the Naka E-Power app. If for a mountain bike with which we tend to get dirty – and the lack of mudguards on this sporty model has something to do with it – mobilizing a phone to lock access to the bike is not ideal, the big one flat remains the absence of lock for the wheels and the saddle. In urban areas, the bike will not last long and some accessories must be added to secure your bike even for short breaks – VanMoof or Mustache offer rather reliable locks for this kind of situation.

The application linked by Bluetooth to your phone records your routes. It takes the information from the very minimalist LCD screen located on the handlebars. Developed by the Nakamura brand, the application is very easy to use but unfortunately you often lose your trip history. On this model, it is nevertheless necessary to lock the bike using a code chosen by the cyclist.
