Advice

[mouhaaa]

Hey guys , need advice for a good conversion kit , my bike trek 6700 with v-brake , front susp only , think it is a good solid frame . What is your suggestion for motor and battery ? Need a range approx 35km and speed 50-60 kph.
I heard about the new 18650 batteries but they are safe? Where can We Buy?

Waiting for your suggestion guys Tx in advance

Grin Technology is the best vendor in Canada, if not the world. The speed you want will need a big motor, higher voltage than 48v. You can get 50 kph with 48v, and a strong 40 amps controller.

What is your budget?

I believe your bike maybe is not a good choice.
With the speed you ask is better a full suspension.

I have a GT karakoram 29er-48v 11000mah(lipo)-30a controller-crystalyte hs3540-15 kilometers range.
Top speed ~64kph straight road.
My weight 80kg.

Many times i would like to have a full susp frame as it bumps a lot after 35-40kph and our roads aren't the best.

At 65 kph + you do want full suspension. But with some care, at 45-50kph you won't do a full blown front wheel stand from hitting a typical manhole cover bump. You might have to tune your rear wheel often though. More comfy ride for sure though, with a rear shock, even a cheezy pogo stick.
