Hello
What are the differences between the strida Evo 3 and the SD? (Besides 3 speeds)?
What is the maximum speed of evo strida March 18 "? 
Thank you very much! 
Hello Driwuoks,
besides the higher weight (maybe ~ 1,5 kg) of the EVO gear drive and the bottom tube (+bottom bracket of bigger diameter) there is no difference.
The 3-speed Strida

Once again, as already mentioned here Strida EVO3 with 18" wheels?,
the question for a maximum speed cannot be answered generally - in principle, I’d say NO Strida will be faster than 0 km/h…without rider…
And I claim hereby also that all my Stridas can be faster than 150 km/h…if I throw them out of an aeroplane window…
YOU are responsible to make a Strida fast, you need to pedal as fast as possible…what’s your usual cadence?
How long can you keep that cadence?
Are you a sportsman?
Currently I have a Strida MAS, which I consider quite fast. Anyway I think that buy you a evo 18". Thank you for answering 
You’re welcome 
if you are fast on a MAS you will be anyway faster with 18 inch wheels, I mean…
Hopefully you noticed the big difference in the gear shifting procedure;
change gears on SD means sideways kicks with the heels
- possible even while pedaling forwards - as you will know
on an EVO you have to pedal backwards for 120 degrees per gear.
I have an SD with 18" wheels and I think based on the numbers it’s faster than the EVO with 18" wheels.
Good to know. In one more week, purchasing tires 18 "for SD =)
Dear Chester, which numbers do you mean?
Hi BSA,
I mean the gear inches of the SD with 18" wheels
Low gear (direct drive)
(80 t / 30 t) x 18"
= 2.67 x 18"
= 48 gear inches
High gear (speed drive)
((80 t * 1.65) / 30 t) x 18"
= (132 t / 30 t) x 18"
= 4.4 x 18"
= 79.2 gear inches
Hi Chester,
yes, thanks to you I’d a closer look and do know better now.
I thought actually that the gear ratios of high/low SD gear would be 100 % equal to the high/low gear of the EVO.
That’s wrong! 
Hopefully you’ll also accept my apology, I’ve corrected that already here:

Hi BSA,
No need for an apology.
