Hiper has been on the electric vehicle market not so long ago, but it is slowly updating its range: the BX635 is a novelty replacing the successful BX630, which has managed to combine excellent road performance and a sufficient level of comfort with the construction of an almost mountain bike.
The Hiper Engine BX635 is structurally very close to its predecessor – large, 26-inch wheels with rough tread, an aluminum folding frame, a shock absorber only on the front wheel, purely optional fenders, a rigid saddle. But all this is complemented by a more powerful electric motor and improved control system.

The Hiper Engine BX635 is shipped semi-disassembled: after unpacking, you need to install the steering wheel, front wheel, pedals, headlight and seat. In principle, the process is simple even for inexperienced cyclists, but a lot has to be done “on a whim” – the assembly (and operation) instructions are not very intelligible and clear, besides, they include instructions for the entire Hiper Engine model range at once, which confuses … In addition, I had problems installing the (optional) fenders – the front one simply did not fit in size, and the promised bracket was not found in the kit for the rear one. The rest of the package was complete, including the necessary tools and fasteners.
After assembly, we get a bike with a low-set handlebar, large wheels with off-road tread and a powerful aluminum frame with rough welding marks. However, the brutal elements don’t stop the Hiper Engine BX635 from looking good – it’s a dynamic bike whose electric essence isn’t immediately apparent. But it is worth taking a closer look – and you notice a thick rectangular frame cross-member (with a battery and an electric motor hidden in it), as well as bunches of wires not hidden in any covers. Nevertheless, there are no questions about the build quality and possible problems when riding in the rain, for example.
The Hiper Engine BX635 is offered in a single color – light gray, Space Gray.
On the left side of the gray aluminum frame there is a hole for the charger – it is protected by a rubber plug, which is quite tight, it doesn’t work well the first time, but it stays in place well.
On the lower edge of the casing frame, in turn, there is a keyhole – it is impossible to activate the motor without turning the key. However, this cannot serve as protection against theft – the Hiper Engine BX635 can easily move on purely pedal traction. So you should immediately get a bicycle lock, it is not included in the kit.
The built-in lock that holds the frame when folded is located on the right side, it is securely fixed and works efficiently – there is no backlash, the frame remains rigid, which is very critical for a bike with near-sport parameters, such as the BX635.
However, another problem appears, which we wrote about in the review of a completely different type of model, the Hiper Engine BF205, – in the folded position, the frame does not lock, it is very difficult to transport the bike in this state, you can only store it. So in transport you will have to move the BX635 in the unfolded state. At the same time, the bike is quite large and heavy, which is almost inevitable for an electric model – its weight is 24 kilograms.
Above the front wheel there is a full-fledged LED headlight with four LEDs, a reflective element is located behind the seat, there is no brake light.
The steering wheel is straight, with a minimum height bar. Along the edges are rubber anatomical handles: on the left are the horn and headlight buttons, as well as the first gearshift unit, on the right, the second gearshift unit – with a lever for downshifting and a button for raising. The Shimano gearshift system has 21 speeds: three sprockets on the front axle, seven on the rear. Also on the right grip is a ring-shaped accelerator.
Near the left handle is the electric motor control unit – this time, unlike the BX630, with a full-fledged screen. It is monochrome here, backlit. On it, three buttons – “plus” and “minus” regulate the power of the assistance mode, and double-clicking on the minus button activates the “cruise control” with a constant but slow rotation of the rear wheel by an electric motor. The central button turns on the system (you need to hold it for about three seconds), and also switches the information shown on the display. Here you can see the speed, the current charge level, the power with which the electric motor works, as well as the mileage and other related information.
The pedals are quite brutal – made of black metal.
The saddle is rigid, covered with black leather-like material. It is only adjustable in height using a key on the rod. And of course, the bike is equipped with a footrest with a door closer.
To simply ride the Hiper Engine BX635, no additional action is required – just sit down and step on the pedals. Despite the serious weight of the bike, it is quite possible to operate it in this mode.
But in order to take advantage of its abilities as an electric scooter, you need to insert the key into the lock on the bottom of the frame and turn it – in this position it locks. After that, by long pressing the “M” key, turn on the on-board control system – and let’s go. The “help” mode is enabled by default at the minimum level, but there are five of these levels in total. Also, the BX635 can work in a mode when you control the gas only with the handle on the steering wheel – to activate it, you need to set the assist mode to “0” (disabled). There is also the aforementioned “cruise control” so that it is convenient to roll next to you or roll the bike down the ramp without exerting effort.
In any case, the assistance mode is always the key for e-bicycles – the thrill that you press on the pedals with little effort, the bike responds with powerful acceleration, it is difficult to compare with something. Moreover, the BX635 is equipped with a 350 W electric motor (versus 250 W for the BX630), so its dynamics are excellent. At the same time, unlike the same BF205, the operation of the assistance mode is predictable and stable – in fact, the bicycle reacts to each press of the pedals, maintaining a speed proportional to the applied forces. No jerking or sudden drop in power. With the same (small) pressure on the pedals with a minimum power, the BX635 motor maintains a speed of about 18-19 km / h, with a maximum speed of 29-30 km / h. You can accelerate faster, but in this case, the help will gradually decrease – to achieve higher speeds, you will need to exert more muscle effort.
There are no problems with the movement up the hill – the bike without tension keeps the cruising speed, without forcing to press on the pedals harder, even with a rather steep climb. This is, however, about a rider of average weight – in my case it is 77 kg. In general, the design is designed for a maximum weight of 130 kg. What the dynamics will be in this case – I cannot say.
Thanks to the large wheels with strong tread and stiff suspension, the BX635 does not only thrive on smooth asphalt roads – where it is quite good and comfortable thanks to the shock absorber on the front fork – but also on bumpy roads or dirt surfaces. I would not say that this immediately sends the bike to the enduro class (lacking lightness), but it is quite possible to ride it outside the city. He holds the road perfectly, does not get stuck in shallow sand.
The complete headlight is bright enough – you can drive at dusk without any problems. The bike is not suitable for night use due to the lack of a brake light.
A single charge of a 375 Wh battery (10400 mAh, 36 V) should be enough for 45 km in maximum assistance mode. I didn’t take accurate measurements, but it felt like it was, or even better – at least after 15 kilometers, only one division out of six disappeared. But I didn’t ride at maximum power either.
The battery is fully charged in 8 hours – for this, a complete charger with a power of 42 W (current strength – 2 A) is used. An indicator on the charger indicates whether the bike is charged or not.
Hiper Engine BX635 is positioned as a city electric bike – and it is really good in this hypostasis: good (and most importantly – even) dynamics, large wheels, a capacious battery, which is enough to get to work and back in assistance mode. A folding design is also provided, but due to the lack of fixation in the folded position, it is inconvenient to transport the bike in this state – so it is applicable only for storage.
At the same time, the Hiper Engine BX635 has great potential for out-of-town riding – a reliable frame, mountain structure, off-road tread, 21 speeds for physical activity lovers and a powerful enough electric motor for those who want to enjoy the possibilities of a scooter. Of the shortcomings, I will only note the need to assemble the bike before the first ride (without good instructions) and a rather large weight – 24 kilograms. Well, and a relatively high price – 59,990 rubles. Moreover, according to promo codeHYPERGO, by following this link, you can get a 20% discount.
