1WD vs 2WD Dnepr

Dear all,

I want to ask some impression and opinion about the 2WD Dnepr. How is the percentage of failure in mixed-use on-road and off-road?

Nowadays, with current speeds and with current road surfaces, is it still reliable product?

 

Discussing with some people, was told me that the rear drive is suffering transverse and vertical load coming from the side wheel.

Traverse load are mainly coming when turning on right and the side-wheel push the rear drive through the shaft.

Vertical load are when there is a big gap between rear wheel and side wheel, for example, one wheel go inside a deep pothole at “certain speed”.

All those load are more severe driving on asphalt (more grip) and if the bike speed over 50-60 km/h.

In off-road since the speed are quite low and the ground is softer, the risk is lower.

My mechanic suggest a small modification on the two joint of the shaft to absorb lateral load, adding some coil spring, but for vertical load there is nothing to improve.

In general, he suggested driving very gentle, especially when turn right on artificial bumps and keep speed below 50 km/h, but then I need double time to reach my destination. :glare:

 

All those issues are not in 1WD, can drive a bit faster and do not care too much of the road surface. But for sure 1WD is less performance in off-road.

 

What is your opinion? Have you ever experienced failure of the rear drive in such condition?

Many thanks :smileywaving:

Pretty deep...

I avoided 2wd because I may/do fly the car about every time I ride the thing...not always on purpose...but mostly!!!

Heard this was problematic with 2wd... and I do Not go thru much more than 3 or 4 inches of snow, so again... not a problem...

 

Also, it should be noted that 1WD owners always fly the chair for minutes at a time when they ride in front of 2WD riders.

(I know I do.. and I'm pretty sure my friend Brian is unhappy about it)
