I have a Woosh Rio MTB since July 21 with 1500 miles under its belt and it has been superb! The gran camino appears to have a similar spec albeit with a 20a controller vs 17a so you should have plenty of grunt. Enjoy!
I have the Thule Europower 915 from Decathlon. A great carrier specifically made for eBikes according to the advertising. Taken both our Step thru and Crossbar Freegos 500 miles to Cornwall and back without a hitch. Well recommended...
The Thule Europower is superb and best price I got by far was from Decathlon store. https://www.decathlon.co.uk/p/tow-ball-bike-carrier-europower-916-7-pins-for-2-electric-bikes/_/R-p-X8364943
Lidls do a cheap one. Its pot luck whether they are in store though as only appear for a week or so when they have the 'bike week' items . http://offers.kd2.org/en/ie/lidl/pcvqK/
When you say "but I struggled with the weight to start with and now 2 surgeries later I am completely floored by it " are you struggling with moving it around when stationary or are you having trouble pedalling it ?
Its primarily the air resistance working against you , the weight of the bike per se is almost irrelevant once moving on a flat road. Up a hill it becomes relevant but only as a combination of rider + bike weight.
Wow I must have got one of the last RIO's in stock as mine was delivered early July. So glad I did as It is a lovely little bike that's for sure. :D Thanks Woosh!
