Components are mostly standard, presumably because it was designed for the army, who could commandeer parts at gunpoint as required, or something. It's a bit big and cumbersome folded for use on public transport.

The most important thing for public transport is that it complies to their rule for peak time travel, ie that it folds. Although the bulk of folding bikes being put on trains are of the Brompton type, as someone who has spent a lot of time on peak time trains, I have also seen the standard bike size folding bike like this being used and put on trains with no complaint from the guard or platform staff at peak times.

I live in rural Ireland. Our winters are dark, wet and the roadsides are often full of thorns after hedgecutters. We dont get that much snow and I generally dont cycle in frost or ice. My idea of a winter bike is full mudguards with additional mudflap extension on front, very robust marathon plus tyres, lights etc. I have found the front hub setup very reliable (no broken spokes) and easier to deal with punctures on either front or rear wheel when this very rarely happen. (I had an Austin mini car back in 1970s so I have no problems with front wheel drive. Interestingly, back then, many people thought that front wheel drives were a bad idea for cars.)

Downtube battery on the bottle cage attachment points and rear hub motor?
Underslung Hailong-like battery:
There may be room for a small bottle battery above a bbs01b?
Frog battery could croak too soon (Land Rover bike)
No:
Front mudguard is available too - I hate that so many folding bikes don't have mudguards...
...like this otherwise lustworthy folder:
Helix - The New Standard in Folding Bikes. Big Wheels. Titanium Frame. Rides Better and Folds Smaller. Made in Canada.
Helix is the new standard in folding bikes. Helix is more compact, lighter, safer and easier to use than any other folding bike in the world. Helix has an all titanium frame and is made in Canada with a state of the art manufacturing process.

They design for California

That strange feeling of "am I doing this or the bike?"
How much are you towing and on what sort of gradient?
Well, they are "250W" as labelled, but are physically bigger than the Bafang G20.250 and have more grunt. The G20.250 is not a bad motor, but the BPM is like one on steroids. Unfortunately, those with a "250W" stamp are like hens teeth these days. This guy not so long ago found one and has had fun with it:
What would be the maximum current I can feed my 36v 250w Bafang BPM motor running at 48v?
Hi guys. I've not posted on here in years. Hope you're all doing well. I'm building an e-bike with a 36v 250w BPM code 16 motor running at 48v in a 26" wheel . The battery is 48v 20ah with a 30a BMS, and I'm using a 48v 35a controller with adjustable current. Is anyone able to let me know...

The mudguards are though pretty useless in function and are just a token , both will do little to stop any crud from smattering feet or the drive train fore and aft.
Most of the battery fixtures in your pictures are in the direct line of fire for for crud from the wheels. I also like mudguards to cover a lot more of the wheel than those. Huge gaps at both the front and back which you would really notice when it was wet.
Mud and crud is like Guiness.. It gets everywhere.
I, ve got big mudguards, by mtb standards, on Giant. Still come home caked in it after chewing through Derbyshire mud. Different to commuting tho, getting scruffy is all part of the fun.. Allegedly.
I agree, quite not good at all.
I wish to avoid looking like I've pissed and shat myself cycling. The Dahon's mudguards are large and effective.
Their "Civilian" models are "Swissbike", some of which I've seen featuring larger aftermarket (?) mudguards, but many don't seem to have rear racks, which is yet another gripe I have about many folding bikes. Dahons of old got that right too, but nearly all lack suspension and disc brakes, and the one which has them (newer Dahon Jetstream), doesn't have mudguards or a rear rack. Annoying. Plus the suspension is pants for anything other than the odd pothole, if not too large or deep.

2 X 25kg + 22 X 2.26kg = 99.72kg water cargo + 15.5kg trailer = 115.22kg + me + bike = 201.32kg didn't make it to the hills, beause the trailer + cargo = 115.22kg weight destroyed an aluminium washer I had fitted because I was worried about excessive wear on the frame from the trailer hitch rotating; pulled out the QR skewer while I was dodging golf balls on a golf course, so I emptied some water out over the golf course and stuck to 76kg cargo max + 15.5kg trailer = 91.5kg thereafter, plus my 64kg bodyweight and 22.1kg bike = 177.6kg total. A particularly problematic hill gets progressively steeper, until I'm crawling up maxing out both myself and the bike, at that's with the bbs01b's 80nm (?) at the crank.
The BPM does sound very interesting indeed, but not for the Dahon. The Dahon is coping fine, does everything I need thus far, including commuting to work on public transport.

I don't mind, as long as the bike is controllable - despite my aversion to offroad (the 2006 Dahon Helios P8 is NOT built for it! Neither is any other Helios), I found myself needing quite fine control while hauling collected spring water to grow my veg up and down hills this summer. A badly or inapproriately set-up bbs01b could have got me tumbling down a ravine.
Being nosey Guerney, why are you carrying water? Fire engine?? Watering the golf course?
The garden I hire to grow veg has no water supply, so I source from the natural springs a few miles away in the hills. It seems to grow veg larger, must be the extra minerals (or pollutants? Probably not, it rises from very deep in a nature reserve, which has a golf course inside it)

I stop periodically because it becomes an obsession, to restart some years later - I swear if the weather is as hot next year, I'm growing prickly pear cactus fruit!
If the obsession is healthy obsession is fine.
If you peel the pears I, ll have some. The prickly bit is a real pain. Nice fruit tho.
There's also a belt drive Montague folding bike, with inadequate mudguards.
