it is because the difference in approach between KT and Lishui. KT let the customers set up the parameters for their controllers while Lishui supplies firmware to OEMs. Being an OEM, I can select which firmware to use to minimise support issues. The result is clear: nobody asks how to change the...

They drink too much of the stuff

You need to test ride the bikes as many as possible because of your lack of space and fitness. Which part of the country do you libve?

Doesn't her fazua have a rear hub kit?# edit: you are right, it has a crank drive motor and a hub gear.

Wheel size doesn't much affect weight though. Katy is happy with the size of her fazua. She only needs a bigger battery.

:D :D if you don't pay income tax, are you still not nicking anything?

I don't disagree. The choice comes down to personal preference.

Likewise, you can go for a 48V crank drive kit if you need more power. The advantage of cranks versus hubs is cranks can take advantage of chainring to cassette gearing while hubs can't.

thank you. I thought he got the bikes mixed up.

You will go faster when assisted, you also need to allow for the power of the motor that may overrun a little time when you brake. The end result is V-brakes at the front is not good enough. They will wear quickly, not just the rubber but also the aluminium braking band on the rim. Best to have...

No, it does not mean that. You asked for EN15194 certificates, I was looking for them where I downloaded before. Manufacturers do not need to test each and everyone of their product. Certificates are only valid for 3 years but manufacturers don't need to get the same product re-certified after...

which green bike are you talking about?

it is possibly because of the comfort of bikes with big wheels. Suspension on a 20" bike will never be good enough for someone with back problems, worse on 16".

You are right! Bafang has changed their sitemap. Same with Tongsheng. The old EN15194 is now replaced with a new certificate, but not for their TSDZ2 like the old one was. TSDZ5 EN15194_Suzhou Tongsheng Electric Appliances Co., Ltd. Motor Meter Controller (tongsheng-e.com)

There are limits to what current technology can offer, even with a large budget. Katy needs a step-through frame, large wheels, large margin on range and a throttle in case she can't pedal normally, extra reliability because it will be her main transport. The Santana3 is really a big improvement...

I will upload their en15194 and ukca certificates here for you tomorrow when I get to the office.

Bafang has obtained EN15194 for their BBS01B kit. Your kit is supplied conform to EAPC rules and as long as you don't change the settings (other than wheel diameter to your correct wheel size), you have nothing to worry about.

The centre of gravity: I agree that hasn't changed. If that's a big issue, a front basket would balance the weight. The issue with the Crusa is it's an American sized bike with wide handlebars, 28" wheels with ballon tyres. It can feel unwieldly if you are less than 6ft tall. The Santana3 feels...

that's pretty average for a step through bike with 17AH or 20AH battery. The single tube step through frame is about 0.5kg heavier compared to the double tube Crusa frame, the high capacity battery is about 1kg heavier than the Crusa 13AH battery. You also have the NEX fork (2.7kgs) about 0.7kg...

Take a look at the Woosh Santana3 https://wooshbikes.co.uk/?santana3 The Santana3 is smaller than the Crusa, very comfortable, stiffer frame, better brakes, 30% more power, 30% more range, easy pedalling and also a little lighter. This is a bike that you can ride 40 miles without stopping if...
