Ariel Rider seems to be faster and has more features. Also Super73 isn't that good for customer service. But in the end, it all depends on your choice.
Hi Court. I am looking to upgrade my e-bike and looking to get a descent controller which can supply 50A continous current. Do you know any reliable one. most controllers I find can only supply 30 or at best 40A
Why not consider M-Class from Ariel Rider. They seem to have fathersday discount. You will get a mid-drive compact e-bike for $1550. Seems like a good deal.
