Review on Children's 2-wheel electric scooter Razor Power Core E90, up to 55 kg, black by Stanislaw Gorka ᠌
The ratio of price and quality is very pleasing, I will repeat the purchase.
The scooter is not mine, it was repaired. When choosing a battery, read the datasheet on it, the first one that comes across for UPS will be three to four times less. The control scheme as a whole is competent and minimalistic, but it is highly desirable to slightly alter it for smooth speed control. It is also desirable to modify the charge circuit, otherwise it is very easy to recharge the battery. Here they are outraged by the charge time. People, a lead-acid gel battery has a standard charging current of about 0.1C, that is, in my particular case, at 9Ah, taking into account the efficiency of about 12 hours. You have, if 7Ah, then about 9-10 hours. According to the datasheet, I have Maximum Charge Current 3.4 A, which neither the battery takes, nor the standard two-ampere power supply can issue. In general, the scooter is excellent, though slightly dangerous without modification.
- Very high quality design and assembly, no backlash, does not fall apart during intensive use. Good appearance. Due to the gear drive, there is a good roll-on, so if the battery is dead, the child can ride like a regular scooter, this one slows down quite a bit compared to the motor-wheel. It is quite convenient to bring it into the entrance, up the stairs and into the elevator, the children can handle it themselves. Weight 10 kg. The wheels are cast, but quite comfortable. Rides with any battery charge, does not turn off. Made in China.
- The main drawback is the button. No speed control. The engine is either on or off. And when it is turned on, then me, a big, adult, is more than 80 kg. the uncle shoots so that he himself is scared, about 20 km / h. I wish my Razor E-300 drove like this. A 6-year-old girl is afraid to press this button. The second drawback, if you ride through puddles, then the dirt is well splashed by the rear wheel into the battery compartment. It is treated by installing a chipper cut out of a plastic bottle under the platform, where it is obvious and clear where to put it. The brake is manual, purely symbolic, a plastic block on the front plastic wheel, you have to calculate the braking trajectory very well in advance. If the brake were more effective, and in children it works better, then there is a danger of tipping forward, the scooter is short.
