For bike repairs I have found it is down to a hands on approach, so converting using kits and working out (with the help of the forum) to diagnose and fault repair items. For me as kid we were also making items and tearing things down to put back together, I guess without knowing it as naïve...

For battery construction a part from info on here which is scant but useful, I have only used one or two sources for research and they were/are Pedelecforum..de and the excellent Endless Sphere. ES is probably the largest resource of what to do and what not to do when it comes to batteries...

KT lcd 3 is a big large for a folding bike so a more discreet one is the lcd 4, it has all the options but in a tiny compact thumb size display.

I think a big thanks should go to Tony @Woosh for his input in to this with the codes etc as not many who are in business would do this freely.

Several options ebay or various China sellers. Controllers & LCD Displays – TorqueTech

Expected range is looking good, charged to 50.1v or 4.175v per cell group or there about's I have only done 9 miles so far and cells are sitting at 3.925v per group. This is in PAS 1 on level terrain so 30+ miles is on the cards to lvc, PAS 1 is only 13% current supply but the increase of 23%...

It's thanks to you and your previous postings of your bottle battery that I used to make mine. The simple genius bit was your use of the cap to glue in the charge port. Though the space looks enough for a pair of 6s balance connectors the lid will reduce it even more so and in reality there is...

Your controller is 24v it will blow if you use a 36v battery, the motor doesn't care about voltage too much. Though as you have a small motor keep the current down a bit by using a 15a max rated controller, voltage will increase the torque power out put so proportionately one can reduce the...

Cyclotricity although they use KT electronics, it isn't the std software programmed stuff we all buy. KT offer custom settings for third party sellers so they have the dual mode controllers that can only be configured by the same looking but software modified LCD's. As vfr says any std KT...

Well done guys :D .

The other main issue to consider besides bike style is the drive system, some riders like the torque sensing crank PAS systems that give more power up to 300% the more effort you can in put. Ideal for those who don't have serious health issues, the other system is cadence PAS system mostly...

Staying legal, opt for more voltage as more voltage means more torque, it also means more speed (but only if used unrestricted) esp on level terrain but for hills torque is where it counts. Look for a 250w 48v bike or kit though there aren't many about. Woosh sell kits 48v 250w not sure about...

As vfr has said most are set for pedal first operation before the throttle engages, I'm surprised this wasn't explained by the dealer or is clear in the manual. My KT is great as one can set it up in the settings for instant use or pedal first use.

We know you are practising because you said so in #1 .

24v lithium yes, the difference will be night and day. Don't forget you will need a 24v/29.4 charger as lithium 24v 100% charge is 29.4v.

You would make a good salesman with your bullshit patter, 'higher spec torque drive' my ass. It has it's place as does a cadence sensor PAS system , it is all down to the system that one is comfortable with.

If you can depending on the bike you will find a 48v bike much more exciting then a 36v but end of the day they all work and give you the ebike smile.

Stop being pompous and take it as advice given. A 36v battery is the nominal voltage which is approx. 50% charged , 36v is 10 cells/groups in series so 36v /10 = 3.6v per cell. Each cell has a min and max voltage 3.1v - 4.2v respectively so a 36v battery voltage range is a min 31v and a max 42v...

It's a thumb throttle, it might not even be connected up yet as to be legal so the connector may be left loose and taped up to or near the controller box or if it connected it may need enabling via the display settings. One will have to refer to the manual about getting in to the settings if...

Sorry guys I never did take any pics of the build as I went along but did get all 20 HG2's inside with 12s waterproof BMS and all the wiring. One of my 36v Sans was able to have the V trim pot turned up to 50.1v to allow cell charging to 4.175v so this is the max I charge to without buying...
