I love the DaaHub and Specialized a beautiful bike, with kit and front motor the balance of the bike excellent...many bikes fall short in this respect. same dapush system as on your Alpino more or less, so similar I expect. deristricted it does 22mph'ish might be the 28 inch wheels. probably faster with you as I am 18 stone and unfit....
the Bosch system like any crank drive very different, certainly not as fast, but very quiet and Bionic in feel, you just push and away. much more natural and nicer when out and about.... I will use it for exercise as you have tpo peddle so a better work out.
the KTM Bosch bike I bought last year, the wife could not get on with the crossbar so got rid, ironically thet have made it a low step bike for this year but it was a lowish spec bike, so the new AVE MH7 nicer. its very comfortable. I tried it at regents park show recently, Dave and all the Kudos lads tried it at a show and it was their favourite bike. I wanted one last year but they were 3k now 2k. fits in camper easily so better security...
MHYBRID
As for which I prefer...... both!lol
Oh! and SB agricultural in comparison to Bosch
