Help! Fiido D21 or Woosh Rambletta

[Bannerblade]

Hi,
I’m looking to buy a folding ebike mainly for use in camping trips so roads and cycle trails.
Looked at a lot of reviews and specs and in my mind I’ve narrowed it down to the d21 or Rambletta.
Ideally I’d try both out but that’s not possible (as far as I know).

Plus points for the D21 are
Weight,
Torque sensor ( I have tried a volt folder with cadence sensors for a very short ride and I found the motor switching a bit strange).
Concerns with the D21 are
Seat post battery seems an easy theft target
No suspension

On the other side the rambletta is assemble in the uk so seems to have better support,
It has suspension (although I’ve never ridden a bike with suspension !).
Battery looks less easy to walk off with.
A bit heavier on the downside and I’m unsure about cadence sensors.
I can’t find any real user reviews of the rambletta although I’ve seen good comments on here.
Would really appreciate any input or advice on this.

that's correct.
I am usually rubbish at explaining things, I found this brilliant explanation on the famous Grintech's ebikes.ca:

OK that makes sense.
Torque sensor for power proportionate to the effort or torque you apply and cadence sensor to apply power such that you don’t notice changes in gradient ( ie effort required to pedal is more or less the same).
If that’s the theory though there are presumably different levels of success in achieving it and dependent on the controller programming as mentioned in an earlier post.
Seems like it might be a bit of a lottery buying without trying first or am I reading too much into this?

that's true but there are other considerations like geometry, quality of the components, cost etc beside the pedal sensor. None of the shops can stock all models so you can compare every aspect.
both cadence sensor and torque sensor are successful. If you are fit and where you live is not very hilly, then torque sensor is probably better. If you have a health issue then cadence sensor is godsend. If you compare the choice to food, it's not like marmite, it's more like how you like your eggs cooked.

I think many of the basic entry level direct drive hub motor kits like violamart have very simple logic in their controllers and were designed from the ground up to be throttle based but when they came to Europe they fitted a rudimentary cadence system which as soon as you start pedalling you get full power, quite exciting but not really that safe and a real strain on the battery with such a high discharge rate. They probably represent the crudest form of cadence system. They don't care how fast you pedal as long as they see you are pedalling. Maybe I've got the last bit wrong and there is some variation in speed for some setups perhaps fine tuning the number of magnets in the bottom bracket cadence disc but for many its a very poor implementation just so they can sell into the EU market and really those kits are purely designed for throttle use which is the norm for the majority of countries in the world.
