If you buy from say PSWPower is it really duty and vat paid.
I ordered a 250W TSDZ2 (VLCD6 display, no brakes, no throttle) directly from PWSPower's website and a 10Ahr bottle battery from their Ali Express outlet.
Both items were shipped from their Germany warehouse - the battery arrived in about 4 wkg days and the motor a few days longer. Both items were delivered to me by Royal mail and there were no additional charges from what I paid on the web.
I bought the items separately to avoid one big costly parcel but of course, there were two postal charges. Whether this approach help avoid HMC charges is not something I'll ever know. I do think though that the Customs paperwork and declared prices by the seller are a lot to do with no Customs charges - and maybe HM Customs have bigger fish to fry than bike bits?
£227 for TSDZ2 and £124 for the battery - so £351 for something that would have cost me a tad over £500 from a UK store.
Now I know what some folk say about Customer Service from UK sellers, but for that sort of saving on what are relatively simple items to fix if the problem is not complex. I'm happy to buy in the way that I did.
