My buzzbike also arrived (this afternoon). I've pretty much assembled it and found it went together okay, including the front wheel. All fixings seemed fine apart from a few loose spokes which I've tightened.
My only issue has been blowing up the tyres! Presta valves - tried four different pumps, none able to get the tyres above 2 bar. I've ordered presta valve adapters from Amazon (that arrive tomorrow) which in theory change the valves to schrader which will make things easier for me.
I think the bike is all ready for the first test when I get these fitted.
I see the buzzbike has been removed from the wiggle and chain reaction websites so I guess they are sold out.
One annoying thing for me is that I emailed chain reaction twice via their website about how I can order spare bafang h700 electrical component parts after the warranty period or a replacement/spare battery - but they have completely ignored both my emails. Can't find these parts available anywhere on the internet..
Update on my Buzzbike:
Got the presta valve converters installed and all is now well - I'm leaving the converters in place so that they are now effectively Schroeder valves.
Took the bike out for first decent ride yesterday - 22 mile round trip mainly on flattish old railway paths and some quieter roads.
-It was pretty cold weather, about 1C when I started and 4C when I finished.
-Average speed was 13.5 mph.
-I only used the 'low' power setting and that was plenty to get me effortlessly through the trip and the uphill sections were easily negotiated.
-Battery had about 30% left at the end which suggests it would probably have done about 30 miles to fully empty the battery.
-I found that the single geared carbon belt drive was fine. I only struggled once and that was when I had to cycle up a very steep embankment from the cycle path to the road after slowing down to about 1mph. It was difficult to get it moving fast enough up the slope for the motor to kick in properly. I need to test it on some longer step hills next though..
Overall, I'm really impressed by the bike.
-I like the understated retro matt black look.
-The frame and components all seem pretty well made.
-Hydraulic brakes are great.
-The combination of the bafang rear motor and cadence sensor seem to work really well together making it very intuitive to ride.
-However, the 700x40 tyres definitely don't like potholes or the Edinburgh cobbled roads and you feel every individual cobble! I may need to think about enhanced suspension options in the future..
