am starting think that two a think it’s like 12 minutes slower getting home from work

Think might go yose power route with built in controller and buy couple spare 36v 13 amp battery and charge at work ready for finishing work by spare charger from them to keep at work

 

If go this route a know motor switch off after 15 mph could peddle to push past that or does the motor stop you bang on 15 mph ??

 

I regularly do around 17.5mph on flat. I have a downhill that when there is a good tail wind I've managed 26mph.

 

My bike is geared with a larger front crank as the original one felt too slow. I also got rid of the knobbly tyres and put on Marathon pluses.

 

The electric power gets me up said hill on the way home and on the flat accelerates the bike to 15.5mph where I take over.

 

If I don't feel the urge to go that fast I don't and let the bike take the strain.

I also have a comedy folder with 20" that I've just converted. I struggled to pedal that up to 15.5mph in the lower assist settings. When I was setting it up I managed 17.5mph on the throttle and it felt flipping dangerous. About 12 to 14mph is a comfortable speed.

For compatibility one can't mix and max controller or LCD/displays.

Lishui and Bafang are hardest to match as often the two components have to be matched form the same supplier, vendors may use differing software then another.

With KT one can pretty much guarantee 100% compatibility , alll one has to chack is the connectors are the same for plug and play, OEM KT stuff may use custom software and settings so one has to be careful if trying to mathc up OEM KT with generic KT.

 

Many of us have used generic KT purchased from various sellers with out seeing any non compatibility issues.

The yose controller will just stop applying power to the motor beyond 15.5 mph, it wont hamper you beyond the mass burden pedalling any faster, so if you could pre conversion you can again post . And with motor assist to get you upto and at 15.5 mph you should have more energy to devote to top end spinning.

 

Ive crossed paths with plenty of folk who would take pleasure in spotting and reporting a 'suspicious' 20 mph ebike, and if you haven't im pleased for you.

 

yose-power employment of either julet connectors or the smt automotive style connectors is basically the generic industry standard that all ebike controllers employ.. the odd brand may add their own twist to monopolise spares resales? and bafang/higo connectors can muddy the waters if unaware, and while there are a couple of known gotcha's NONE apply to yose-kits afaik so rest easy on that score..

 

Topbikekit can even sell you a 48v kt controller that fits inside a hailong battery base, if you buy one? I for one would lurve to know if its a dual voltage capable 36v/48v device or just 48v as the site description is a bit ambiguous.

- the more compact space than within the 'silver box' format, could limit circuitry options??

 

Making an ebike travel at 20 mph isnt difficult, the question to ask yourself is however is it a wise thing to do?

And if traversing areas unpopulated perhaps it is but on the same roads day in day out?? -

Perhaps if your the most courteous and polite fast ebike on the road givng NO-ONE any cause to raise an eyebrow you will be ok??..
