I am using my Okinawa Ridge+ (Lithium battery powered) since 6 months. Odo shows about 1800 km. I really enjoy riding it. I like the silent, smokeless, smooth electric motor. The power and speed are okay for casual single drives. Ridge+ can handle the bad and slopy roads fairly well when the payload (driver+luggage weight) is about 60 to 70 kgs. I can drive my Ridge+ about 50 kms after a full charge. Top speed I could reach is about 45kmph.
On the other hand, after the purchase - at least for few days - I felt that I have been cheated by Okinawa. It's speedometer, odometer and battery indicators are not completely useless. Speedo just boasts about 10 km (20%) more speed. Odo adds additional half km for every 1 km you drive i.e., if you run 1 km, odo display is about 1.5 km. Battery indicator says battery is full unless the battery is discharged to 50%. I almost stopped watching trip meter.
If you were used to drive a petrol powered 2-wheeler at 60kmph or more, you will feel helplessness for couple of days. But you can adjust - sooner or later. You have to re-learn clutch-less driving especially stopping in the middle of a steep slope. It is easy and within a couple of minutes you will do good. Top speed is always limited to about 45 kmph (or to 55 kmph as per my Ridge+ speedometer). Acceleration is smooth. But, you may feel no response at times while slowing and speeding up. In other words, you have to turn the throttle to particular angle to reach particular speed. You will notice slow but steady decrease in the speed and power as the battery gets discharged. Don't even attempt riding while battery indicator shows a single bar, unless it is an emergency. Power and driving range are two limitations you should keep in mind. Headlight is a bit dull but probably okay for the speed. You will miss disc brakes. However, you don't need to change oil like you do for petrol 2-wheelers. There is no chain or clutch to cause major wear and tear. Ridge+ is a true gear-less 2-wheeler. Even during the heavy rains Ridge+ showed no engine issues. My dealer is very kind (Ujire 2019) though he lied at times. Overall, I love riding this EV.
