    Any e-bike kit can do 8% hills. The XD kit is about twice as good as an ordinary kit on steep hills. With your weight on 20" wheels, the XD kit can attack 20% hills without or with little pedalling. if you find the BBS01 a bit expensive, the woosh GSM crank drive kit is £249, not much more than...

    Winter prep for chain driven ebikes

    The OP's got a 09 battery. The output connector is just above the drain holes but water can still get in through the USB socket and the charging socket. I'd put some Lithium teflon grease in and around all the sockets for good measure.

    hub motors are limited by their RPM. XD motors have maximum speed around 21mph-22mph on 26" wheels, if you want to mount it on 20" wheel, you'll also need 36 spokes of the right length and your maximum speed will drop to about 17mph. For 20mph on 20" wheels, you'll need a 328rpm hub motor or an...

    Custom ebike kit vs ready built

    you leave the bike, go to the sea front for fish and chips then come back and collect your bike, but you'll need to book with Andy @ Woosh first. Middle of the week is best.

    Custom ebike kit vs ready built

    Scott Sportster 50 ladies: as you are only 75 miles from woosh in Southend, it's probably worth your while to bring your bike to them and have it fitted. They have a selection of bottle batteries that they don't advertise, let them fit a few rivnuts to your downtube and choose a bottle...

    Custom ebike kit vs ready built

    the GSM has a bit more torque when pushed hard. The rack battery on the Big Bear LS is 15AH, same capacity. The HL battery can easily be mounted on a seat post rack, but seat post rack is easily nickable.

    Custom ebike kit vs ready built

    you could ask woosh to supply you with a rack battery, it costs about the same + £20 for the rack, like this one: http://wooshbikes.co.uk/2014/bigbear-ls/mini/saddle.jpg Alternatively, Woosh GSM CD kit is £100 cheaper than the BBS01 and has a bit more oomph too (18A controller on GSM, 15A...

    Need a bottle battery

    the OP wants Samsung cells. That bottle battery on ebay has Chinese cells. If I were the OP, I would upgrade to a 15AH HL battery if not constraint by budget. http://wooshbikes.co.uk/?batteries#batkit

    Winter prep for chain driven ebikes

    Keep the bike in a dry place as much as you can. The only weakness I know of is that the LCD may fog up with humidity, if this happens, dry it with a hair dryer or rice grains.

    Custom ebike kit vs ready built

    I know woosh in Southend will fit crank drive kits for £50, hub kits for £75. Just don't mention going off road to Hatti! (the boys are OK with offroading).

    Custom ebike kit vs ready built

    building is not difficult, most people can do this themselves or call in a mobile bike mechanic for a couple of hours. but if you can't look after the bike yourself, then you should perhaps look into buying from a local bike shop.

    Custom ebike kit vs ready built

    you may have to buy a German made bikes for offroading. AFAIK, none of the Chinese batteries has good enough mounting kit to last the rough rides. Keep in mind you want a powerful motor with throttle, your battery is going to be at least 3kgs. The downtube batteries are a bit better but you'd...

    you need to lash the pieces together then paint the wire with epoxy resin to waterproof the repair and make it permanent. I use cheap pound shop two part epoxy glue. Something like this will do the job...

    Kalkhoff Integrale 8

    there are also reports like this one that the belt breaks. http://singletrackworld.com/forum/topic/belt-drive-i-t-may-be-time-to-admit-defeat The chain may stretch but that is much more predictable than a belt that may break at any time.

    BPM (big powerful motor) is made by Bafang. The ordinary e-bike hub motor is geared and usually have 120mm diameter. Members tend to call them SWXes, the reason being that the most polular motors are SWXes made by Bafang since 2008. Maximum torque of those 120mm motors is about 45-50NM and the...

    Battery Voltage (42V) & Charging Voltage (42V) Questions.

    motors don't work like kettles, not much is static besides the motor constants. The coils have very low ohmic reistance, about 0.01 Ohm to 0.1 Ohm, you can confirm it with your meter. When the motor spins, the coils generate back EMF voltage which is proportional to the RPM. Without this back...
