Where can you find an inexpensive battery for an electric bike?

No, you don’t want to find an inexpensive battery for an electric bike. Lead acid electric bike batteries are cheaper compared to lithium batteries but they are very heavy and they may not last very long.

This is an ebike with lead acid battery installed.



Also take into consideration rider’s weight if you intend to buy lead acid batteries just because it is less expensive. Electric bikes are not designed for driving with a heavy load, especially up steep gradients. The motor may get overheated and its fuse or circuit breaker will blow out. It may also damage the speed controller if overheated coils on motors are not replaced on time.

You should want your electric bike batteries to be small or light but powerful and safe, in the wattage that is acceptable in the country you are cycling.  At Jom Johan we do sell ebikes with lithium or lead acid batteries installed with 1 year warranty on the following parts:

1) battery
2) charger
3) motor
4) controller

We will be happy to advise on what is best for your requirement and budget.

Is it legal to change the speed limit of an electric bicycle?

In Malaysia we follow the standards set by UK for power assisted bike. The legal maximun power output is 250W with an acceptable speed limit of 25km/hr. It must also be pedal assisted with a speed reducer installed.

You will have to apply for a license to ride your ebike if it exceeds this limit and you will also need to wear a helmet.

I would advise customers who would also like to ride their ebike in Singapore, to consider getting one with power output of 200W as that is the acceptable limit there. Choosing one that is also foldable makes traveling with it more convenient.

You can read the full details in this presentation I created.

Going electric on your bike is...

Going electric on your bike is going to be easy once Rubbee, a rechargeable electric drive, is in the market. At 6.5 kg (14 lbs), it is definitely light for a conversation kit.

So, what if you do not have any skills in electronics and mechanics to mount it? Will it be possible to have it mounted on your bicycle "in just a few seconds", as claimed?

Watch this video and decide for yourself.

 

 So, what is its limitation? I can't see any as long as the throttle is connected.

 

 Rubbee is a KickStarter project with 17 days left to reach their goal of raising £63,000 to get it moving.
