Hello I recently bought a Giant Lafree that didnt come with any batteries. I did some research and figured out what the original batteries where. My problem is is that I want to upgrade to lithium batteries and I dont know how much wattage my motor is or what I should run for a battery. I posted here because this is my last resort as I havent been able to find any info on it. Thank you so much for reading.

You will also need a BMS for the lithiums. This site might have some useful info https://tinyurl.com/ycpo57qx

Thanks. Does that battery come with the bms? Also how do i figure out if my bike is 100~132vac or 200~264 vac.

Thank you again.

If you read the description of that pack, it says "12A continuous discharge current BMS".

As for the question of charger voltage, whatever AC power you have in your country.

Here's the user guide for that bike as well:

Also, this from another forum might be of interest:
Thanks to UK Electric Bikes l Pedelecs, there's quite a bit of information about these bikes on their forum. The early Giant electrics, like the Lafree were popular in the UK.
They have a viable link to a service manual for an early SLA powered Lafree Sport which will have some good info for you.
Just a word of caution, our shop has worked on several of these and due to the lack of original parts for an unusual motor setup, these can quickly turn into money pits.
