Get an e-bike that has pedals, you can buy a Wisper bike and they will get type approval for it so you can use the twist and go/throttle.

Best contact Wisper for advice whether in or out of warranty David the owner is very passionate about his brand and is a very helpful person.

Legit ones in S pedelecs class will come with certificate of conformity to make registration easier, no certificate means self certificating via the SVA route.

Sram hub gears have a weak link in them , they seem to be prone to breaking and even worse on leccy drives bikes. Probably one reason why they stopped production last year as others do it better. Alfine 8 I use on a mid drive and abuse it by going lower then the 2:1 ratio inducing higher...

We like a bit of leg pulling humour.

Yep, hello Mike.

First of all good luck with that one and welcome to the Fora. Not familair with their batteries so don't know if you can simply stuff probes in to the discharge to check voltage, battery likely should be ok but may have a blown fuse. Fuses can be ext or int. Help regarding Kalkhoff's will be...

No load speed in PAS 5 is currently about 27mph with P1 value 86, I don't know the BBS01 motor ratio. To set P1 I will have to go out with my Garmin satnav to set this correctly so as to read the correct speedreading. PAS 5 showed about 696w on the screen using rear brake to draw current...

Having tested all 36 combo's and carrying out several battery disconnections and start up sequences, I'm happy that I have the best sequence for the wiring and finally fit the male pins in to the mating hall connector. At this stage the connector isn't necessary and directly soldering wires...

The white 5 pin jst hall wire connector to the motor needs to be kept, 5 of the hall wires from the motor wire will need joining to the jst. The motor will want syncing so you will need to have M/F connectors first to do this, I used the standard J7061 hall block as I have a few spare. Red &...

Firstly order your controller. https://www.aliexpress.com/item/36V-48V22A-Electric-bicycle-standard-sinewave-controller-Light-function-water-tightness-cable-KT-Series-500W-conversion/32857864688.html?spm=a2g0s.8937460.0.0.6ff22e0eJxWANF I chose a 9 fet signwave KT 22a model all with Julet...

Welcome Uwe, Nearly any bike will be Ok for fitting a kit whether hub or mid drive better if it has hydraulic disc brakes. Your main decision is where to carry the batteries (which type/chemistry ?). Which bike depends on your use off road /on road and whether a trailer is being towed. As an...

Different tyres have different compounds, some a bit softer then others.

Brake discs /pads ?

I will try and post some pics later and a description of work. Due to the rubbish weather again today I set about wiring up an external KT controller to my BBS01, several hrs later a total success ad now just need to go for a ride out to check all is ok.

You can test the current/torque on a stand by using throttle and using the brake by nearly stopping the drive, keeping an eye on the watts on the LCD you will see each PAS level has a different W output. With P3 set to speed mode you get max current/torque with each PAS level, each level will...

The cheaper batteries will use China cells, fakes or genuine branded cells but not the best ones. Current share will not be the best and possibly plated steel used for interconnectors rather then pure nickel. Jimmy uses a range of the best cells available and copper interconnectors and all at a...

2 or 3 years ago now my brother paid £280 for a Bosch Gen 1 recell, Jimmy upped the ah from 10.4 to 13.8 using Panny GA's. I had a soft pack made for £250 24v 7s/15.9ah using Boston 5300mah cells.

There is no indexing on hub gears, the rear cog/gear is a single one and relies on internal ratios for gearing. Likelihood is a chain length issue or if using a tensioner it may be out of alignment or bent. If bike uses horizontal drop outs or an eccentric BB then adjustment is likley needed...

With a smaller wheel size speed reading it would be under reading, if you were able to do so and could pedal at 16.8mph indicated your actual true speed would be faster.
