Neomouv is a French company based in Sarthe which has been developing electrically assisted bicycles since 2003. Today, the Neomouv range extends from the urban electric bicycle to the all-terrain model, including the folding bicycle and the typical cycle. hiking.
The Kalyso 2 is one of the most advanced in the brand’s range of urban electric bikes to date. Like the latest Neomouv models, the Kalyso 2 uses a Neoassist 2 motor, developed by the Japanese company Vinka, placed in the crankset. This develops 80 Nm of torque, for solid and progressive assistance thanks to the torque sensor. Three options are available for battery capacity (468, 562 or 612 Wh) for advertised ranges ranging from 60 to 100 km.
The Kalyso 2 is only offered in one frame size (46 cm), but in 2 wheel sizes (26 or 28 inches). The smaller diameter is suitable for riders between 165 and 175 cm, while the larger will allow a rider between 170 and 185 cm to be comfortable. The most affordable model has a 7-speed derailleur transmission and V-brakes and starts at €2289. For 210 € more, Neomouv offers to switch to hydraulic disc brakes. An additional 140 € extension will take you to a Shimano Nexus 7 transmission and its rear hub with integrated gears. We tested this latest version, equipped with the 562 Wh intermediate battery in 26 inches and sold for €2,839.
Comfort and ergonomics
The Neomouv Kalyso 2 adopts the form of an open frame bike and ignores the top tube. A geometry that facilitates the ascents and descents, particularly when carrying a child in the back or when our clothes do not lend themselves to flexibility. The central Neoassist 2 motor, placed in the crankset, is not the most discreet that we have seen, but it remains relatively compact.
Admittedly, a central engine is common at a price that is close to €3,000, but the battery housed in the luggage rack is much less so these days. Most e-bikes in this price range opt for downtube or seattube integration. The rear and relatively high position of the almost 4 kg battery shifts the center of gravity of the bike, causing it to lose stability against competitors like the O2Feel iVog City Boost 6.1.
However, this place grants certain advantages such as easy access to the battery and its removal to recharge it separately; practical when you want to park your bike in a place where you do not have a socket for recharging and to avoid having the precious accumulator stolen. The Kalyso 2 battery slides easily into place and its position is locked with a key.
The build quality of the bike is decent overall. The welds at various points of the aluminum frame remain quite visible. The open frame imposes on the Kalyso 2 a fairly massive diagonal tube, decorated with a few patterns. Some elements are of lesser quality, such as the plastic mudguards, the handles or the chain case.
Elements that still have the merit of being present. The mud flaps do a good job and drop low enough with their mudflap to avoid dirtying the shoes in wet weather. The chain guard and the chainring guard, for their part, leave the bottom of the pants far from any trace of grease. Essential points for an urban bike intended to be used in particular for commuting.
Like most open frame bikes, the Neomouv Kalyso 2 offers a fairly upright riding position. The stem can be adjusted to adopt a more or less dynamic position, but comfort remains in the line of sight. The hanger is quite curved and helps keep the arms close to the body. We mentioned it above, the handles are a notch below in terms of finishes. Admittedly catchy, they turn out to be quite uncomfortable in the long run. The right handle even tends to slip a little on the handlebar and we had to replace it several times.
In terms of comfort, the Kalyso 2 will be more suitable for cycle paths and very smooth roads than for paths and other paved areas. Indeed, despite a Zoom Aria fork offering 45 mm of travel, vibrations are quickly transmitted to the arms. The choice of 26″ Hutchinson Urban Tour+ tires that are just 1.5″ wide doesn’t help with cushioning. On the other hand, this type of thin tires promotes performance. If you want to venture on paths, the choice of wider tires will be essential.
Regarding the seat, comfort is also limited. The saddle itself strikes the right balance between softness and support. On the other hand, the absence of suspension of the seatpost requires lifting the buttocks on the slightly bumpy passages.
The Kalyso 2 illuminates in front of it thanks to an Axa Compactline 35 light which emits, as its name suggests, 35 lux. All in all, fairly average and rather directive lighting that will be suitable for an urban environment with public lighting. At the rear, the brake light is posted on the luggage rack and can be seen effectively by other users.
The luggage rack is properly integrated and can accommodate loads up to 25 kg. A crutch is present as standard on the left side of the Neomouv Kalyso 2. The latter being fixed to the rear base, it will be necessary to avoid overloading the front of the bike with a basket. If the frame of the Kalyso 2 has what it takes, the French brand has not chosen to integrate a frame lock.
Neomouv has developed its own motor, called NeoAssist 2. A central motor which is housed in the crankset and which is relatively compact given its promises in terms of performance. This motorization displays 250 W and no less than 80 Nm of torque. A torque that surpasses that of a Shimano E6100 (60 Nm) fitted to an iVog City Boost 6.1 and which guarantees effortless hill climbing.
Motor assistance can be adjusted to 5 levels. The first two provide light support suitable for those who like to put in a bit of effort on flat rides. The 3rd and 4th levels allow for slightly more lively departures and are pleasant to use in town to get the best out of traffic and get sharper pick-ups. The 5th and last level gives the full measure of the engine’s power and will be especially useful when tackling the climbs without sweating.
Overall, the management of the power level delivered by the engine is pleasant, thanks to the torque sensor. This provides assistance correlated with the force exerted on the pedals. The cyclist therefore maintains a relatively natural pedaling. However, the 27.5 kg of the Kalyso 2 does not really help to take the machine beyond 25 km/h, the speed at which the assistance is cut off. The raised driving position does not, however, really encourage sporty driving. The range of development is quite limited and we spin quickly in a vacuum past 28-30 km/h.
The management of the assistance modes is done from the control box which integrates the screen. The “+” and “-” keys make it easy to navigate from one level to another. The information communicated is quite limited and goes to the essentials: instantaneous speed, level of assistance chosen, remaining battery capacity and distance travelled. We would have liked to find an estimate of the remaining range in kilometers so as not to be trapped by the 27.5 kg of Neomouv’s bike.
Our version of the Kalyso 2 is the most upscale and can count on a Shimano Nexus 7 internal gear hub. This eliminates the need for a derailleur and the rear gear cassette and therefore possible derailments. In addition, changing gears, managed by a twist grip, can be done both while driving and when stationary. This requires less anticipation of gear changes, which is appreciable in town with the many changes of pace. However, the Nexus 7 requires you to stop pedaling briefly for the gear change to take place. A hit to take.
Braking is provided by a duo of Tektro HD-M275 devices and 160mm disc, front and rear. These hydraulic brakes offer satisfactory precision, good progressiveness and bite that allows braking in just over 3 meters on dry ground (for a load of 95 kg, rider and bike included). It’s okay, without being dazzling, but average for electric bikes in this range.
Finally, when it’s time to push your bike alongside you, a walk assistance mode is offered by the Kalyso 2. By pressing the “walk” button, the motor provides electric assistance up to 6 km/h . Useful when you have a few meters to go uphill while walking next to a bicycle loaded with luggage or with a child.
