I use this one: https://www.amazon.com/gp/product/B01N8SJ9CK/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1
Yeah it's heavy but it works so amazingly well. Btw, you don't need the cable & that'll reduce some of the weight. It does come with a u-lock mount that you can attach to your scooter or bike.
thanks again, i'll take a look. i'll be storing the bike in my garage and rarely lock it up in public. i have one of these Kyroptinte locks which i think is okay for < 1-2 hours locked up.
whats the difference between the FX1 and FX2?
i was looking at the FX1 from this shop: https://www.northerncycle.com/product/trek-fx-1-300275-1.htm
