Thanks
@dodgeman once I receive the bike, I will try and tie the peak design backpack with bungee cords. If it does not work, then I will buy
Vaude eBack. It is 28L and has plenty of space for spare clothes, a padded laptop compartment and other pockets. I am looking into a lock now, helmet, MIK compatible trunk bag and grocery bag as well for personal commute to explore the city and supermarket trips. The Specialized Mode helmet looks good and is rated number 1 as the best urban city helmet according to the Virigina tech institute so would go with that.
I decided to go ahead with the Specialized 2022 Turbo Como 5.0 in black colour. I have paid the dealer $1000 refundable deposit and they reckon that at the most, it should be delivered by Feb 2022 which is ok with me as I will not need to use it to commute to work until end of March 2022 anyway. Really excited and looking forward to
