This post is going to teach you hopefully everything you need to know about choosing, buying, registering, and the basics of driving an electric motorcycle, e-bike, electric bicycle, 电动车,电品车,电动自行车, or any of the other wacky names that may refer to what I simply refer to as ‘dian dongs’. I do not recommend using this word with Chinese people as they simply will not understand what the hell you are talking about.
Type:
There are three basic types of dian dongs that I will describe here. These terms I use are all of my own creation, so don’t expect them to be universally understood.
Motorcycle type: These come in a few different sizes, but they basically look like little motorcycles or mopeds or vespas or whatever. They often (but not always) have a rear storage compartment, headlights, rear view mirrors, no pedals, alarm, anti-lock breaks, cruise control, speedometer, steering lock, rear wheel lock, turn signals, horn, and can (legally) seat two adults, but are often seen with as many as four people on them at once. They have a range of up to 40-60km depending on battery, and top speed is controlled by a built in speed regulator which is often illegally removed. Legal speed regulators allow up to about 37kmph in my experience. Advantage is their many features, disadvantage is they are the most expensive, and they are the largest and can be harder to find parking space for. The bikes voltage rating controls how fast is can accelerate and how much it can handle weight. I’ve seen voltages go from the 30′s to the 70′s, the most common being 48 volts.
Hybrid type: These look like a cross between a bicycle and a motorcycle. They typically have a special, separate seat in the back with a second pair of handles for the back seat person to hold, have much less of a physical profile (not as wide) and sometimes have a storage basket in front. Pedals are also optional. These types cost slightly less than the motorcycle type, but often lack features, and can only seat 2, legally or otherwise. 3 out of 4 times you see these on the road, it’s a woman or girl driving, and they often have children sitting on the back seat. Men tend to avoid these, must be a fashion thing.
Bicycle type: These are bicycles. If you look closely however they do have a very simple battery and motor. These are becoming quite unusual on the road, and the ones you see tend to be very old and in bad shape. I suspect that these have gone out of style in general. They will often not have headlights, mirrors, horns, storage, alarms, or any other features besides being a bike with a battery. Advantage is their low weight (Just the battery and frame) and profile makes them easy to park in small spaces.
Brands:
There are a billion brands of bikes out there, most of them are total crap however. I was personally recommended by several people and numerous Chinese language websites to buy Xinri brand, as they are of the highest reputation for quality. They are also the most expensive. Other brands I see a lot on the road are heping, emmelle, and yadea. There is a brand I saw called LDSAMSUNG but honestly I don’t think they are related to Samsung, the Korean electronics company. I saw one bike that was labeled in English as “OFFROAD 4×4″. Obviously, they don’t know that 4×4 = four wheel drive.
Prices:
Prices range from the mid 1500′s to 3000 and up. For a good bike, you should expect to pay at least 2800. I personally paid 2899 and apparently mine is the low end configuration of my model. The high end version (different battery and supposedly better shocks, was around 3300). For reference, a good non electric bike is around 800 RMB.
Batteries:
There are two numbers to pay attention to. Voltage and Amp Hours. A pretty standard basic battery will be 48v 12Ah. A slightly higher capacity will be 48v 16Ah. Basically, Volts is the power, how fast it accelerates, handles multiple passengers, handles steep hills, etc. No matter the voltage, it will still stop accelerating once it hits the speed regulators top allowed speed. The amp hours affects how long it can run for, and is essentially distance. Typically, 12Ah = 40km, 16Ah = 60km. I personally have found this to be fairly accurate, as I can drive to work and back twice on one charge of a 12Ah battery, and the distance is 9km each time. All batteries on the market are lead-acid based, and as such you should avoid fully discharging them, leaving them empty for long periods of time, and when charging give them a full 12 hour charge. After market batteries can be bought at lots of different shops, but beware of cheap knockoffs and batteries that lack overcharge protection circuits. You can buy a battery with a large amp hours rating, but always use the same voltage as your original battery. To charge your battery, your bike will have an outlet, and the battery can also be removed and brought indoors to charge. These things weigh a ton (mine feels like about 3 bowling balls). Some bikes may also use two smaller batteries, instead of one big battery.
How to drive:
This is a complicated subject, but I will do my best to simplify it. Basically speaking, there are no official rules. Dian dongs are almost completely unregulated. People break the rules constantly and suffer no consequences, even when the police are standing next to their bike as they zip off through a red light. Regardless, for your own safety, I suggest you follow the below rules:
1. Stay in the bike lane unless there is no bike lane, or there is something blocking it. If you can’t ride in the bike lane, you can go onto the street, but stay as absolutely far to the right as possible and go slowly. Watch for cars when outside of the bike lane.
2. Stop at red lights! And even when its green, be wary of cars that will try to turn in front of you. You technically have the right of way, but be careful as people here can be selfish assholes. Some intersections have a special traffic light just for bikes. Give that top priority. You can also look for a pedestrian crossing light as a reference for when you can cross. Legally, you are just a pedestrian on wheels.
3. Drive in a straight line as much as possible. If you want to move to the other side of the bike lane for whatever reason, check your mirrors/behind you first. Someone may be trying to pass you, often someone with no speed regulator and that is wearing headphones and generally isn’t paying attention.
4. When passing someone, if it looks like they aren’t paying attention or are swerving, honk first. This isn’t considered rude, and even if it was, you should do it for safety reasons. Two quick honks is usually a good method.
5. Be ready for anything. Anything and everything can and will happen in the bike lane. It is completely unregulated and uncontrolled. Pedestrians will often walk down the center of the bike lane despite there being a wide open sidewalk next to it. Cars will park and drive into/out of the bike lane. Be especially weary of parked car doors that can suddenly swing open. If possible, stay away from parked cars.
6. Let people pass you. Especially men, they tend to be the worst drivers. Just let them go around you and zip off, don’t let them bother you. At a busy intersection, don’t get caught up in a wad of other bikes, let them all pass you first, then you can go and pass the slow movers. Wads of bikes are very dangerous. Women drivers tend to drive slower and safer, but at the same time they do not make any effort to actually watch where they are going. Sexist as it may seem, let men pass you, but try to get ahead of women so they don’t suddenly swerve in front of you and make you crash.
7. When stopped at a red light, stay to the left, people will want to turn to the right on a red (legal) so give them space.
8. Don’t flap your arms and legs everywhere when stopped or in motion, people will zip past you within inches of your bike, don’t let them hit your arms or legs. This happens and people can get seriously injured.
9. Watch for people driving in the wrong direction, for some reason they will stick to one side and expect you to move if you are on the same side as they are.
10. Always use your headlight when it’s even a little bit dark. It’s not about helping you see, it’s about making you more visible to cars and other bikes, especially bikes going the wrong way.
Maintenance issues:
1. Check your tires for proper air pressure. Add air when needed.
2. Adjust your mirrors each time you ride, they get bumped around a lot when they are parked.
3. Pay attention to your brakes. If they start to squeal, get them fixed/replaced.
4. Battery life will decline over time, if the bike no longer holds a charge long enough for you, get a new battery. Recycle your old battery!
5. If your bike is just a useless piece of garbage held together by duct tape, sell it for a few hundred RMB and get a new one! They aren’t that unbearably expensive.
Last but not least…
Licensing:
In Suzhou, you need to get a little license plate. The shop that sells your bike can probably do this for you on the spot. It costs 8 yuan, and you need to have your ID, and know your address and phone number. They can help you put the plate on (I had to ask them directly, only then did they help). They also might have different hours for the registration office than sales. When I bought my bike, the registration office was closed (I got mine at RT mart, the office closes at 5, but sales are open until 10pm). So I had to come back a day later to get the plate. Keep the receipts and such that you get when you buy and register your bike. If you want to sell your bike, you need this stuff to transfer it legally to a new owner. Expect the price of your bike to drop at least 40-50% when you resell it. You might also consider buying a second hand bike from another expat, check on the wanted or for sale ads in the local expat boards. Sometimes other students who are leaving Suda will sell theirs to you, but it seems like you need to have connections for this.
