I did not mean to suggest to you the Gallego instead of the Zephyr-B. Woosh sell 4 folders, the 10AH 20" wheel Gale that suits almost anyone, the crank driven Zephyr-CDN for taller riders and steep hills, up to 6ft, the Gallego for people who would be interested in a Gale but need a lighter...

if you need a good bike in small package, the woosh Gallego is very lightweight, folds very cleverly, can be pushed about on its rack wheels, and comes with its own carrying bag, could even go into airplanes (youmay need to remove and check its small battery in as hand luggage). semi-fold...

@morphix - your posts sound extremely enthusiastic, my initial reaction is to urge caution, especially when investing large amount of your own money. Fundings and grants have their own uncertainty. good luck and my best wishes to you and Lynda. Happy New Year.

the Zephyr-B will cope with your weight and height with ease.

I hope the business model will work for you. I remain skeptical about the scope for obtaining CO2 reduction grants and subsidies. BTW, deferrement facility (if you need it) costs you typically 1% of the amount.

I agree totally. While the UK have not officially adopted EN15194, all those big hubs including those laser marked to 250W may not be legal after all. Some smart lawyers may insist to measure their output power the old fashion way.

The battery can take 2C without much to worry about, you can go up to 48V 24A on your battery, that's why I suggest BBS02 48V 18A 500W. The Sirocco CD is limited by the controller, rated 36V 14A. You can extrapolate the difference. The BBS02 is just as efficient as the BBS01, about 75% to...

that's why I suggested the BBS02 48V 18A 500W. You can build a far better bike than the Sirocco CD that flies up hills at 15mph with hydraulic brakes and good suspension for not a huge budget. Maximum speed is about 30mph.

With regard to maintenance, that's my personal view. Punctures: in favour of CD because you can have QR on both wheels, brakes: in favour of CD because the wheels have less total inertia, shocks: also in favour of CD. There is a situation at the moment that manufacturers tend to fit hub bikes...

of course they do. But that does not change the common observation that broken spokes affect mostly rear hub motor wheels. People who use hubzillas on ES are also very experienced builders. I believe that crank drive bikes are easier to maintain and statistically require less maintenance.

they are just trying to confuse you. Power applied to hub = risk of breaking spokes, More power to the hub to climb your steep hills increases this risk. the bad road surface makes this risk into a near certainty.

you don't have to push the 500W motor, but the power is there when you need it. The 500W motor is only a little heavier.

8-Fun BBS02 48V 18A 500W would be a good match for your 48V 12AH battery. It's twice as powerful than the 36V 15A 250W Woosh CD motor that is on your Sirocco CD.

thanks d8veh for the information. When I test rode the 36V 250W version off the XD, I wasn't convinced but I now think this 48V 350W kit is the best kit in 2015.

how much does the bike cost you in total?

IEC plugs and sockets are not a good choice for batteries. After reading Morphix's ideas about making his own batteries, I'd like to point out that battery cells need to be welded or soldered, not to save money but for safety reason. Welding gives the lowest internal resistance, soldering is...

the BBS01 is the easiest kit to fit.

put grease in/around the output connector, brass prongs and along the path where the battery slides in/out. The grease also helps to to protect the prongs against sparking and corrosion.

Jonal, welcome to the forum. You can probably get everything else on that sort of budget apart from the battery. May be one of the vendors here could give you an old battery for nothing if you ask them nicely.

I test rode the Zephyr-B last month for about 20 miles, there was about 30% left in the battery at the end. It's very light, despite having a big BPM motor, handles well and extremely comfortable. Full suspension and remote lockout control for the front fork, you can adjust the suspension to...
