The amazing SpiderTrac suspension is now even more amazing. The new 2.0 version, that can e.g. be found in the QUICKIE Jive M² Sedeo Ergo powered wheelchair, incorporates two additional performance springs that provide an even more intuitive response. These springs help all 6 wheels maintain better contact with the ground when moving onto or off of ramps and curbs. It’s simply something you have to experience to believe.
