Re: Taken the plunge.

Although my first post here have to agree with Eddie. There are only 2 legal BBS's both 01 or 01B versions they are factory stamped as 36 250w 15a or 36v 250w 25a. The factory settings/parameters are usually set to be very tame mainly to prevent controller issues and warranty claims, to get the bes...

Re: E-bikes: depressing or what?

Depressing why ? People have got legs they can walk but choose to use polluting cars, rather then bus or train. The use of ebike has now cut my car use down to under 1k miles a year now. We all have some sort of central heating but before the 70's was a rare commodity most relied on an open fire or ...

Re: Converting using a e-front wheel.

Depending on how heavy you are ( 90/100kg or more ) then you will ideally need a high torque Bafang bpm hub, these are 4.4kg 180mm quite heavy hubs on a front wheel. They do produce some wheel spin on loose or slippery surfaces but nothing to bad, they excel at hill climbing. the 201rpm code 13 bpm ...

Re: What happens above 15.5mph?

Above 15.5mph you go faster :D . All my bikes have China kits on them bar one which is an s - pedelec. All the China kits can be manipulated to ride with assistance above the cut off, as long as you pedal well and hard no one is bothered. The only time you will get noticed is if you use a throttle w...

Re: Electric Bike Conversion

Roadies are the hardest to even speak to when change comes along, they don't accept that other riders have differing needs or requirements. In their eyes if you don't sweat or go red in the face at the point of bursting a vessel then you are not cycling, no pain no gain. Ebikes can allow for a gentl...

Re: Q: How much resistance when motor is OFF

My error didn't read the post correctly.
My bbs01 is similar when unpowered the slight resistance is probably down to the internal gearing, though like a hub you are still riding a bike that is heavier and weighs about the same with a battery as well.

Re: e bikes and effort

Twist and go is legal though you need to pedal to activate it whilst riding, other wise they are only meant to 4mph /6kmh walk assist mode when not pedalling.
Saying that 4 of my ebikes are all configured via the set up menus for max throttle op at all times.

Re: Should I buy Oxydrive kit?

I have seen that kit as well though not interested. like to keep an eye on what's available. It uses the bafang hub motor, new kits usually cost £5- 600 so it would be reasonable if you get if for under £250 but don't get carried away bidding. As with all used kits the big iffy is the battery and ho...

Re: Converting using a e-front wheel.

A touring /racing bike is usually fairly light and a heavy front hub motor can vastly affect the handling of said bike, depending on how heavy you are it would be better to fit a rear hub drive with a down tube battery for better weight and c of g distribution. Unfortunately lighter weight kits aren...

Re: What's best for a hilly area?

Bafang bpm or SWXO2 hubs are awesome and very powerful an equal to any mid drive on the road for hill climbing look for a 201 -250 rpm speed motor rating. A cadence/pas sensor makes for a nicer ride esp if your legs get tired as it only requires a gentle pedal rotation to kick in to whoosh you along...

Re: Circe tandem pedelec conversion kit.

I notice a noob error in the hub fitting the cable exits vertically if it rains any water will run down in to the hub and it will rust and seize up, you need to undo the wheel and rotate the axle 180 degrees so that the cable forms a drip loop fo water to run off. Doing it that way also means you ca...

Re: Speed sensor vs torque sensor

The only kit I know of with torque sensing drive is the Tonsheng TSDZ2 mid drive. Wisper bikes /amps bikes of Kent produce the very well regarded Wipser torque range which have dual mode, the bike has 4 torque drive sensing levels but in addition has cadence level as well. David Miall is the boss an...

Re: Kudos Cycles - Sprint

Lifepo4 is slightly old battery tech but has a greater life span generally then modern lithium ones. The reason fro being older tech being is that they are quite heavy compared to lion celled batteries. Nothing wrong with that however most lifepo4 bikes ten to be 25- 30 kg in weight. Kudos bikes are...

Re: Cargo Bike Electric

As stated the legal motor rating allowed is 250w with out over heating but a decent 250w hub can handle 600 - 700w max out put. The power output is delivered by a combo of the battery and control 36v x amps = watts so a 36v battery combined with a 15a rated controller = 540w nominal at the hub this ...

Re: e bike info

You need to show a pic of the bike .
Also if the motor is brushed or brushless count how many phase wires go from the controller to the motor.
It it has 3 you are in luck if not you aren't.
