Rider impressions

I confess I was extra cautious when I first got on the A1 Pro . I like the bike ’s industrial coming into court , but its eminent - spec components put me on guard . I would be OK if it had a tender throttle and rapid acceleration , but I wanted to be quick if it withdraw off like a rocket ship . When I review the fantabulous and very immobile dual - motor , dual - wheel driveAriel Rider Grizzly , I learned that e - bikes build for speed must be handled with caution .

The A1 Pro ’s design include practical features such as IPX7 waterproofing , making it suitable for rides in all weather condition conditions , and its C belt drive offers durability with minimal upkeep . These features , combine with the bike ’s full-bodied construction and various capabilities , make it a reliable fellow traveler for both escapade seeker and daily commuter . I wish it included stock mirrors and become signal , which I consider necessary for frequent town and city rider , but those are my only misgivings , and mirrors are an easy add .
