The workstand looks excellent for the money but the clamp looks fiddly and won't be much fun trying to operate with one hand whilst holding a heavy bike in the other. It won't be a match for a park tools stand but it could easily be better than a £70 stand from Wiggle or eBay.
The top tube on the bike in the picture is quite thin by todays standards and you may well find you can only fit the seat post in the clamp. It's got nice touches like a magnetic tray and a handlebar stay, at £30 it's well worth a try.
The panniers are OK for occasional use but when I've had similar they don't wear well and are not waterproof, I wouldn't spend £15 on these but pay the extra for good
roll top panniers.
The tool box is OK for a standard bike but most problems I've had on an ebike won't be fixed with these. I have a 20mm adjustable wrench, a multi tool with screwdrivers and a decent set of long hex keys, plus a puncture kit and most problems can be fixed at the roadside.
The foot pump looks good but my experience of Lidl pumps tells me it's almost useless. The gloves will be OK for slightly cold days but get too hot quickly when riding, in wet or freezing weather the gloves will be very inadequate. Spend money on Sealskinz instead.
The cycle computer is probably good but will probably reset itself on very cold days.
I started with most of my cycling gear from Lidl and Aldi and it's very good to get you going on a budget, I got through a very cold winter with it but as bits have worn out I've upgraded many and it was worth paying more for better kit. Most of my clothing still comes from the two shops, it's good for stuff you wear in layers or summer but the extreme weather protection is not so good especially as small items are not expensive in other places.
