How to have 2nd freewheel on my bike

[nobtiba]

Weight was not my initial concern, SAFETY is my concern.

In most countries, it is totally illegal to carry any passengers on a bicycle that is not expressly made for that purpose, (such as a tandem bicycle also known as a "bicycle built for two"), for obvious reasons.

Adding a motor to the bike now adds a further dimension to this scenario.

It is just plain dangerous as just one unforseen accident can cause serious injury or even death not only to you but the children as well.

You are right. I will be the one who is most concerned about this. Thanks for the detailed explanation too. So I should use the motor only in the purpose of carrying the market items then.

He is in Singapore so I have no idea how the authorities may look at this over there...Remember though that Singapore still uses "caning" as a form of corporal punishment...I am sure that would be quite a deterrent to would-be law breakers...lol.

Caning in Singapore - Wikipedia

en.wikipedia.org

They have dedicated bicycle lanes and enforce speed restrictions, as well as require a theory test for e-bike riders, making it a safe environment for all commuters. However, being overly strict can lead to the need for adjustments to accommodate all parties. For example, when regulations are too stringent for e-bike users, some may resort to finding alternative routes because e-scooters greatly assist them in their daily lives, making it difficult for them to give it up.

Am I assuming correctly that you are Japanese residing and working in Singapore???
I came to that conclusion based on your screen name here on the forums which appears to be a Japanese name using our western alphabet.

You can also buy pull behind trailers designed to carry children in.

I still need more detailed instructions on how to use the motor with the chain for the movement here.

Any one can help?

First we need to know what kind of engine you plan to use.

Ok so you have one of the electric zip motors not a gas engine. Those motors are pedal assist only. You can get a triple sprocket freewheel and attach a larger sprocket to one of freewheel cogs.
