I had issues with the bike that was sent to me direct from Magnum. It arrived, and was labeled as 250 watts (the sticker on the controller compartment), and it performed as such. It was slower than my 350 watt folder. I also had to file an A to Z claim to get my refund. This is why I suggested buying from a local dealer. Your experience may be better than mine.

My experience was indeed better than yours Michael Mitchell.
We had a pre-disposed notion that we would buy 2 e-bikes from a well-known online retailer but without being able to test ride, I was reluctant to do as potentially unwinding (returning) 2 mail-order ebikes at best seemed like a possible giant PITA and who needs more of those in their lives?
So, we attended a semi-local (70-ish miles each way) open house which was being hosted by an e-bike centric shop, and even attended by the one and only Court (I learned about the event itself on this forum in-fact) and we were graciously allowed to test ride any number bikes, which we indeed did.
We tried a number of them of all types, but concentrated on the folders since thats what we'd be buying. Besides the Tern eLink which was slightly out of our price range (X 2 bikes) and lacked a requisite throttle, the Magnum Premium 48 we tested performed the best, and felt the most solid to us. Thats the benefit of the test ride....there's is usually an "X" factor which cannot be experienced on paper, through just published specifications (or even through video reviews alone for that matter). We decided to buy them, the Missus selecting the "lo-step" version and me the "manlier" (I kid) hi-step.
One of the two had to be ordered, our lbs didnt have them both in stock.
When we DID get the bikes a week or so later, and began riding them together, and comparing notes we discovered that I required nearly double the ped-assist level as my wife to enjoy the same performance (and the same we both agreed we tested). She rode mine, and I rode hers and also agreed they performed quite differently.
We drilled-down into the computers of them in attempt to equalize them, and were unsuccesful. We called Magnum's office (not our lbs, as he wasnt open yet, and Magnum was being 2 hours ahead timewise. We did let our lbs know what was going on and he seemed grateful for the input) and told Cory the technician there what we were trying to do and he suggested that our bikes might have different manufacture dates and probably different controller firmware. He had us open the controller compartments and verified this to be the case.
Here's where I believe Magnum and their staff really shined customer servicewise:
Cory put Jesse on the phone who mentioned that they had NO controllers in stock, and a several week wait was in order. I groused. He THEN volunteered to provide one from a showroom unit, shipped it nearly overnight, I installed it myself, it completely solved the issue and I returned the original to them by mail. (Please note...it didnt perform "badly" just not as well as the other. Without a second to compare to I would not know the difference)
So....my experience with them going the extra mile, seriously to provide great customer service was 110% positive and I am both grateful to them for doing so, and now very pleased with BOTH of our Magnum Premium 48 bicycles.
YMMV
