Tyre type & size

The L1-1 and ES2 adopt different approach for tyres selection. MOBOT L1-1 uses front 8.5″ pneumatic and rear 8.5″ pneumatic tubless tyres. On the other hand, Ninebot ES2 uses 8″ solid and 7.5″ solid rear tyres. Solid tyres do not have the suspension effect unlike pneumatic tyres. As such, the ES has incoporated front and rear suspensions to cushion the ride.
On the other hand, solid tyres have its advantages: they do not puncture. But it costs much more to replace and may not easily available at your neighbourhood scooter shop.

#Doyouknow: You may wonder why MOBOT L1-1’s tyre looks much larger than ES2 when the difference is only 0.5″. This is because tyres rating uses nominal diameter. In other words, the measurement is taken from the tyre middle line to opposite middle line.

For the rear brakes, the L1-1 uses mechanical disc brakes with the ES2 uses fender (or step over) brakes which are similar to manual scooters.

For front brakes, both the L1-1 and ES2 use electronic anti-braking system (E-ABS). The only difference is ES2 E-ABS is triggered by the thumb brake located on the left of the handlebar. For the first timer, it will need some time and practice to get used to front drive + front brakes: press too much and you will fall forward. Press too little and the e-scooter takes too long to slow down.

#Doyouknow: E-scooters usually do not just come with electronic brakes as these type of brakes may malfunction when there is some electrical issue like damaged battery or circuit.
