Razor E300

Advantages: Batteries are easily changed. Inflatable wheels. Folding steering wheel. Ease of service.

Disadvantages: Heavy. Lead acid batteries. Noisy. Rear wheel mudguard required.

Comment: Only 7Ah batteries are suitable without replacing the charge controller. I tried to set it to 9Ah - they do not fully charge. Regular tire inflation increases the roll rate and, as a result, the cruising range, the dynamic characteristics are noticeably improved. Driving through puddles is fraught with splashes on clothes - I installed a mudguard from a piece of sheet rubber. I installed a bike computer. My weight is 80 kg. The maximum speed is 18 km / h in a straight line without a slope. Mileage to full discharge 21 km (with new batteries). After so many years of use, I decided to replace the batteries with lithium ferrum. After the replacement, the range has tripled. The weight was reduced by half. I also put a voltmeter from aliexpress. The main problem with this scooter is that it has a 24 Volt motor. 15-18 km / h is the limit for him. Modern models go 30 ... the next step is to install the engine at 36 volts, since the chain drive allows this.

Advantages: I took this scooter off my hands. The assembly and materials seem to be of high quality, although there is no engine protection, although they write everywhere that there is. The price tag is not space, but significantly more expensive than the e100, which is the same, only for teenagers, although in the states the E300 costs from $ 200. Charges pretty quickly, about 6 hours full charge. The handlebar brake is quite comfortable and reliable. The instruction is in Russian, you can even download it on the internet. The wheels are penvmatic, so they smooth out the bumps in the road a little, although there is no suspension. The weight is quite small, 20 kg, but I did not find any handles / carrying devices on it, but I adapted myself like that.

Disadvantages: Engine power is not ice, my weight is 71 kg, even up a small hill drags sluggishly, you need to help him. The battery is also not so hot, although it may have already been hooked up, it takes me less than 5 km until it is completely discharged. There is a ratchet, but for some reason it rolls not very much even down the hill, if you do not put pressure on the gas, it starts to quietly slow down, it is hard to ride it after discharging Akum, it is easier on foot, although this may be the problem of only my copy. I did not find a single club of owners of this device on the network, so there is no one to consult with. I tried to look for batteries for replacement, mine cost 2 7Ah, on US trading floors there are even 9Ah compatible for $ 40 2 pieces, but they are quite heavy and most likely the delivery to the Russian Federation will come out as much, we could not find anything adequate yet. I keep the device on the balcony, where I don’t know where to put it in winter, the instructions say that Akum cannot be kept in the cold (I thought I’ll take them off and put them in the warmth), but at the same time it says that from time to time the scooter needs to be charged and use as little as possible during periods of long-term downtime, I don't know how I will do it yet.UPD: After pumping the wheels, the scooter went much better and faster and took longer to discharge, but the sensations on the bumps became more furious :)

Comment: In general, the device is not bad, but Akum would be more capacious and the engine is also more powerful, they write that it carries up to 90 kg, but I think there will generally be 2-3 km. By the way, you can't jump on the curbs on it, the ground clearance is very low, you can hook it with the engine or with a battery, you have to choose a path where there are fewer exits and arrivals to the curbs, in general it rides on smooth asphalt much more willingly than on paving stones or wavy asphalt - the wheels are still small ... In terms of speed, I get it 2 times faster than walking, that is, it is slower, but the scooter is more compact.

Advantages: Excellent, durable, solid scooter.

Disadvantages: Heavy, large (the hatchback does not fit into a small trunk, only in the rear compartment), the steering wheel does not fold (it can be removed entirely but at the same time hangs on the wires, throttle and brake handles), weak battery.

Comment: In general, the scooter pleased me, it runs quite fast at 20 km / h (without any alterations). rolls both one and two with his wife with a total weight of 115 kg on the asphalt perfectly, quickly. A charge for two is enough for 45 minutes with intervals of 2-3 minutes. Fully charged in 6-7 hours.

Advantages: The most important advantage, I think, is what emotions this scooter delivers, the coolest thing is to watch the reactions of pedestrians, sometimes looking at you like you are naked. Pulls even the two of us with my daughter (130 kg in total), we decided to try, despite the limitations :) for 15-20 minutes we skated with her, though it was very difficult for him to climb the hill, he had to help.

Disadvantages: Too heavy, the child will not cope with carrying.

Comment: Fair price in the states, of course, but still worth its money.

Advantages: Kondovaya iron construction. Rides softly. Good cross-country ability, rides both on Sobyaninskaya paving stones and on the ground. Sufficient power. Wide platform, comfortable to stand with two feet. A handlebar high enough for an adult. Low cost of maintenance and modernization. Good balance for carrying up stairs without folding the handlebars. Good roll-off thanks to the ratchet on the driven sprocket.

Disadvantages: Well very high noise from the chain tensioner. Poor placement of the engine power wire, in the battery compartment, the battery rubs the wire insulation with its angle, outside the engine power wire is placed in front of the engine in such a way that it suffers primarily from any obstacle. The engine power is not regulated, either it is turned on at full, or it is turned off. The wires are qualitatively soldered to the batteries and, in addition, are filled with compound. The charging circuit is strange, there is no battery balancing, if one is not completely conditioned, the circuit will charge it at least up to 18 volts, that is, it will burn out completely until the battery case breaks. It was not possible to inflate the rear wheel without disassembling the scooter, even with the help of the extension adapter included in the kit.

Comment: I took a used one inexpensively with obviously dead batteries, there are two of them, 12V 7Ah each. There are options with a folding and a removable steering wheel, I got it with a folding one. After the Speedroll E5 small scooter, heaven and earth, it rides softly, fast and far. The truth had to be tricky. Replaced the soldering of the batteries with terminals, put in good batteries with a glass separator, high current and hydrogen recombination, redid the wire placement.The next step is to solve problems with noise by replacing or removing the chain tensioner, bringing the ratchet to a minimum rolling resistance, installing a power-adjustable controller, a balanced charge of batteries and other pleasant electronics, equipment with universal power, both from standard lead-acid and lithium batteries, there is an idea make an external connection of 18V batteries from a screwdriver. The bottom line. For a grown man. Women and children are heavy. I did not notice the need for shock absorbers in practical use. If you take a new one, then you roll up the batteries, injure the wires and sell them for inexpensive. For handy lovers of technical creativity there is scope, the basis is good. Real mileage with a load of 90 kg. reaches 12 km. with good non-standard 9 Ah batteries.

Advantages: Reliability, speed, ease of operation and maintenance, structural strength, conveniently located on the scooter, wide inflatable wheels (does not fall through, smooth running)

Disadvantages: Low location of the electric motor (you can damage it on obstacles if you carelessly)

Comment: I really like the model (appearance, design). Optimum price and quality. I use it for trips to and from work. Service life -1 year. Without comments. No options - I think this is the best model in its class. I recommend to all.

Advantages: Everything that the manufacturer promised is there!

Disadvantages: Heavy

Comment: A very comfortable "machine". We ride with my child in the country together, I go to work myself! (7 minutes). And just to ride it is a great pleasure.

Advantages: fast, comfortable to ride, and in general it is cool, the coolest scooter :-) :-) :-) !!!!!!!!!

Disadvantages: heavy

Comment: cool and fast

Advantages: Reliability

Disadvantages: A heavy and small power reserve in the scooter's passport says 20 km, in fact 10 km I would like to increase it just I don't know how to do it attacks voschem and generally normal

Comment: You can drive around the city from home to work, charge up and back Dima

The son was delighted when they gave him a scooter. Well done. Acceptable in weight. Easy to operate
