BBS01 is tiring and saps strength unassisted. Probably best used in low assist even on level terrain but you won't know this till you have ridden the conversion. Lifepo4 is a bit old hat now we have lithium ion, which is somewhat lighter then lifepo4. Though you can look at Eclipse bikes for...

With hub motors you need to select highest assist for hills and then they romp up them easier, much better if you use 48v and 17/20a controllers then they have plenty of power.

Stock is currently 0 so is why you can't order it.

#55 I posted a link direct to there site, EU warehouse is in Berlin.

This is the I use it has not julets so you need the rest of the kit to go with it pas, lcd , throttle etc as connectors are SM ones...

When I got my kit they only listed 36v, but now they list a 48v 350w rear kit so no need to mess about with another controller. The 17a KT will give good poke and if you wanted more amps you could carry out a small shunt mod with a little solder. If you wanted to use 36v hub with 48v controller...

I run the dual voltage with 36v on outward journey and then 48v on the home bound journey, controller distinguishes the difference effortlessly.

Yes hence it is for 48v, you could and would also be ok with 14s.

It is a Yose kit. The controller is KT 15a 36v, if you run it at 48v you will smoke it as the main inrush cap is only 50v rating. You have to ditch the controller and get a KT dual voltage model, the hub is excellent at 48v in pas 5 at 20a, the other levels are also good and pas1 19/21mph is...

Compared to the 20a dual KT controllers the S12S also a KT is massive.

Only problem with Yose hub you have to buy the whole kit where as Q128c you don't. Q128C is about £130 delivered + duty, YOSE kit is about £180 though you can sell the controller and lcd3 and pas etc to bring costs down. LCD, controller etc should sell quite easily for/as 36v replacement items...

Don't get me going on phones, I find them totally alien. PC2017 beat me to it. SD or phone will show up under 'my device' in 'my pc' in Lhs pane You should be able to save transfer pics to pc or directly select a pic to down load..

Parts probably no but a pic may help. Other wise its a new case or mount or both. https://www.ebay.co.uk/itm/Frog-Type-Electric-Bike-Battery-Holder-For-Viking-E-go-Eco-Stepper-Hopper-Etc/163217215670?hash=item26008110b6:g:NS4AAOSwf4pZyoUw...

Pics should be simple to upload, once saved to your pc pics file. In the reply box select ' upload a file'. It will auto go to my docs on your pc , select the pics tab on the Lhs pain. In pics select the file then open , then select the pic and open . It should then upload to the reply box you...

52v is 4 more cells are needed over 48v, though would/should fit in same case. Advantages for using higher voltage using same 3450 GA cells. 36v 5p 10s = 50 cells. 17.25ah / 621wh. 48v 4p 13s = 52 cells. 13.8ah / 662wh, +6.5%. 52v 4p 14s = 56 cells. 13.8ah / 717wh. +15.5%.

Wh is more important then ah. A case that holds 50 cells for 36v will hold 52 for 48v. As long as the cells are exactly the same 48v will have more Wh/range then the 36v one even though the 36v one has a fifth more ah.

o_O Eddieeeeee, have a word !!

20700 cell price to high in my view so 18650 for me still.

Using good cells help currently for price I'm using PF but future builds will use GA.

In use the you will see battery sag so it will dip lower then 47.6 underload once voltage has decreased but once load is reduced it will bounce back, I use rest V's. Once it sags below reduce load applied and use lower assist to mollycoddle the cells instead of stressing them. For 48v I use to...
