1What's the motor weight?
The weight of the motor is 4Kg for the 250W and the 500W versions, 4,5Kg for the 749W and 999W versions. The battery weights from 2.8 to 3.2kg.
2Which kit I should choose for my FAT bike?
You can choose all the different power versions and select the option "FAT" into the "Bottom Bracket" section of the webstore.
3What is the diameter and length of the motor?
Diameter is 195mm, lenght is 54mm, including the double chainring.
4What is the Q-factor (width) of the crank?
The Q factor is increased of approx 50 mm. Lower Q factors are for optimizing the leg push, larger Q factor are best to prevent knee injury. The extra thickness is equally distributed on both the bike's sides, keeping the pedaling symmetrical.
5Will chainline be appropriate?
Yes, the chainline will be perfect because the chainrings are in the same position as in a standard bicycle.
6Can the system be operated without a using smart phone?
Yes of course. The smartphone will need only when you'll have to adjust the motor's parameters. Once the motor will be set as you prefer, you can leave the smartphone at home and enjoy your trip. If you still want to have the phone with you on the bike but you're not interested in using your personal device for obvious reasons (possibility to falling, exposure to water and bad weather), we offer you the possibility to purchase an IP68 device, equipped with our App.
7The crank set on bike has 3 chain rings where as the motor has only 2, does this mean i would have to replace the front derailleur and gear shift?
No, it will only take 5 minutes to setup the front derailleur by tuning the adjustment screws on it. You should take a look at BikeItalia's video, explaning the mentioned procedure.
8Is the 120Nm torque measured at the chainring or at the back wheel?
The torque is measured at the chainrings.
9How can the different power versions have the same 120Nm torque?
The same torque is a result of the use of the same stator for each power version. The different winding allows to obtain different speeds at the same torque. The Power is torque times speed so this explains the fact that torque is the same but the power not.
10How did you get more range out of more powerful motor? (999W estimate range, greater then the ones from the 250W)? Shouldn't the 999W consume more?
The more powerful motor comes with a high capacity battery (550Wh). Plus you have to factor that the range of the motors is not listed at their respective maximum power but at the constant speed of 25Kph, so at a constant output power.
11The battery doesn't fit my frame, how can I do?
We have recently introduced a production partner that creates custom batteries. You only need to send an email to email@example.com with your frame measures (a photo of the triangle with the specification of the dimensions is also ok) and we'll proceed in sending you a quotation for your custom battery.
