>>1838796I have a Riese & Muller Packster 70 cargo bike. Pic related, but not with all the gay components in the pic related (more on that in a minute). A few points since I've had mine for about 3 years now, and use it daily.
The R&M and Larry & Harry bikes are the two primary brands which have riding geometry which mimics a mountain bike position. You're more leaned over/toward the bars. Your picture is a direct geometry off Dutch pedal bikes and IMO not comfortable at all and you sit very upright with your legs way out in front of you.
Purchase the longest bike you kinda can't afford. In retrospect, I wish I got the Packster 80, but there were none in stock and I needed one ASAP.
Bosch has easily over 80% market share for batteries and motors. However, the 3rd Gen Cargo-Line motors are absolute fucking trash. I am on my third one under warranty and all I am doing is hauling around a 4 year old, some toys and a few bags of groceries.
In general, the frames and the electronics are where the money goes, components be damned. On the Larry & Harry you can get one out the door with full XT or Saint components...but they also use Shimano motors, which may be hard to service. My R&M frame is made very very well, but the components were fucking garbage. The Tektro brakes were not robust enough to slow down the weight of the bike loaded in a safe manner. Usually the front suspension fork is some 20" POS off a kids mountain bike and really, will blow out sooner than later. I am on my third fork. The wheels and hubs are usually Deore. Components are usually all Deore.
To deal with the brakes, I went from a 160 mm front disc to 220 floating Hope and rear being a 180 mm to a 203 floating Hope along with XTR 4-pot calipers and 9120 brake levers. Drive train is a mix of XTR and XT with the chains being SLX. You will find that the basic parts offered on the bike out the door are inadequate for the weight of the bike fully loaded.
