Surviving Winter With Your Electric Bicycle

Fri, 24 Mar 2017 23:46:21 +0000

During the winter season, people often find it hard to use their electric bicycles as much as they do in summer, particularly during rainy weather. We thought we’d provide 6 top tips to help you get the most out of your electric bicycles, even in the rain.

6. Keep warm – This seems pretty obvious, but it’s still worth mentioning. Get some gloves, a warm jacket, warm pants, a beanie under your helmet and you’ll have a much better time. A lot of people don’t realise how useful gloves are.

5. Stay bright – in winter, lights are even more important than usual. Remember: lights are there to help you be seen, rather than to help you see. Make sure that your lights are working.

4. Frequent Lubrication – the cold, rainy weather shortens the time your lubricants stay effective. Make sure to frequently lubricate parts of your bike - such as your chain - this winter. Just make sure you don’t get any on your brakes!

3. Slightly deflate tyres for better grip – if you’re going to be travelling through slippery road conditions, you can take about 5 PSI out of your tyres to get more grip. When you do this, you soften your tyre. With a softer tyre, you get more of it touching the ground, and so you get more friction, and more grip.

2. Plastic bag for seat – one really common, really annoying thing about using bicycles in rainy weather is wet seat. Wet seat is when you leave your bike in the rain, and your seat collects water. We recommend getting a plastic bag to place over your seat when you aren’t using it. Not only will it protect your seat from the elements, it’s also a really cheap and easy solution to an annoying problem.

1. Mudguards – this might not be surprising, but we’d say mudguards are one of the most important quality-of-life bicycle accessories for wet weather. Most people will have mudguards, and for a very good reason. Make sure you have working mudguards. You won’t regret it.

Tips on how to get best mileage per charge on your electric bicycle or electric scooter

GETTING THE BEST MILAGE PER CHARGE FROM YOUR ELECTRIC BICYCLE OR ELECTRIC SCOOTER

There are many factors that prevent you from getting the optimum distance per charge on your electric bike or electric scooter. These include actions like using full throttle all the time, accelerating flat out and constantly varying speed. Other factors can include incorrectly inflated tyres, headwinds, towing, heavy loads and hills.

These tips should help improve your distance per charge.

Always charge your battery daily after using even for shorter distances as this will keep your battery in better condition and help to avoid sulphuration.

Check tyre pressure regularly and keep within 5 PSI of maximum pressure. Tyre pressure can be found on side wall of tyre. This also includes the tyre pressure on trailers if towing.

When accelerating do so at a steady increase and try to avoid rapid increases in speed.

Don’t hold the throttle fully open, back off slightly after reaching desired speed. This will improve mileage with little lose of speed.

Use the pedal effect system as much as possible especially on hills and long upward gradients,also always pedal assit on take off. Back of the throttle when going downhill.

Keep brakes adjusted correctly and remember new electric bicycles and electric scooters with drum brakes may need a few trips to allow the shoes to bed in slightly to enable proper adjustment.

SEALED LEAD ACID BATTERY FOR ELECTRIC BICYCLE & ELECTRIC SCOOTER OPERATIONAL MANUAL

CHITUMA ELECTRIC BICYCLES USE TIANNENG BATTERIES IN LEAD ACID APPLICATIONS

Tianneng sealed lead acid batteries are made specifically for electric bicycles & electric scooters to the PRC standard GB/T22199-2008

BATTERY CHARACTERISTICS This battery is a lean liquid valve sealed type and can be maintained for restoring stored energy charge.The small amount of gas produced during recharging is oxidized inside the battery.No acid fog can be seen under normal conditions and only a tiny amount of gas is lost . The battery features a large storage capacity , less self discharging , high specific energy , long performance life with a safe and reliable operation making it the premier electric bicycle or electric scooter battery.

INSTALLATION INTO ELECTRIC BICYCLE etc If the battery has been in storage for over 1 month in order to compensate for any energy loss charge the batteries using the e-bike charger for 4 to 5 hrs after the charger light has turned green

BATTERY DISCHARGING When the electric scooter or bicycle is started the battery begins discharging . The battery must not be over discharged, the under voltage protection of each 12 volt battery is 10.5 volts . 36volt controllers are set at 31.5 volts and 48 volt controllers at 42 volts .

BATTERY CHARGING SLA BATTERIESFor maximum battery life it is recommended that the battery is recharge when 70% of stored energy is discharged or the total continued milage exceeds 70% of the battery stored energy allowance . only the charger supplied with the electric bicycle or scooter should be used . the smart charger used will charge in 3 stages. The first stage is a constant current of 1.8A , the second stage is a constant voltage charge of 14.8volts per 12 volt battery ,the third and final stage is a trickle charge stage of a constant 13.8 volt per 12volt battery

SAFTEY PRECAUTIONS

1. It is recommended that the battery be charged daily after use ( ie ride it today ,charge it tonight ,turn it off tomorrow morning)
2. Only use the approved charger supplied with electric bicycle or electric scooter
3. Make sure the charger is turned off at power point before connecting or disconnecting
4. When charging the battery status lamp should be red ,changing to green when charged
5. When the E-bike is not in use the battery should be kept fully charged.and be charge at least once a month to prevent the pole plates from becoming sulphated causing premature failure
6. The battery must be adequately ventilated not placed in a sealed container,must not be subjected to naked flame , water,fire or exposed to direct sunlight.
7. If battery casing is cracked , damaged or leaking it must be safely disposed of and replaced .
8. The electrolyte is acidic and if splashed on skin must be wash immediately in clean water.
9. The battery shall be charged at an ambient temperature of 10 – 30 degrees or damage to battery can occur resuling in sulphating or thermal runaway causing battery to expand rendering it unserviceable

10. Do not short circuit.

11. Do not open except bu professional maintenance personnel
