Hi Nancy and Tiniover Team, I received the backrest today and installed.. TY, I have included several pics and videos that express how much you and your team have provided a true miracle in the Tiniover Creek Pro Trike. As you will hear first hand how my wife has gone from being a prisoner to her terminal illness to now having hope again even though my wife Kimberly is currently in Hospice Care. Prior to me learning about the Tiniover Creek Pro Trike we researched countless Trike options from numerous manufacturers that didn't have the innovations or safety features that my wife needed. The various configurations that the Creek Pro Trike offer such as the ergonomic Back rest for superior Back support for someone who is disabled with balance isssues or experiences syncopy...or from sudden motions.(Turning and remaining upright) Another feature my wife is looking forward too is,the Rear Passenger Seat so our Grandson can ride in behind her which is a "Major Safety factor"for someone who is disabled or just elderly who might have diminished stamina capabilities and needs to have an able bodied co-pilot available! There is also the folding of the trike for easier storage, the trike itself is quite heavy @approx. 125 lbs + & 6' in length... however that is actually another positive feature due the solid steel construction of the frame assembly. There are so many other features such as,3 wheel hydraulic brakes for superior stopping power, 18"x4.0"in-nova tires that grip the road surface in a superior manner, PEDAL Assist mode 1-3 with a sustained top speed of 15 mph, The Rear Passenger Seat that has the necessary an innovative "ANTI-Tipping Bars on the back of the Trike to compensate for the added weight distribution behind the axle. The voluminous Rear and front Baskets with liners that are made from Tubular Steel. Construction, The Front Fork suspension with non adjustable dampening but still manages to absorb many unforeseen "Pot Holes"from the Roadway. A handle bar and stem assembly that has 3 primary adjustment to suit any rider that may or may not have a disability that can be tailored to their specific needs.,the Direct Drive Motor is 750 watts with 1500 watt peak.Coupled with a center axle differential that is driven by what looks like to be a motorcycle chain. Let me just some up the bottom line...The Innovative Safety features on this TiniOver Creek Pro trike rival units that cost 2-3 times as much.The Team @ TiniOver are Top Notch professionals that are making much larger players in the e-Trike market take notice that there is a new option now available that will rival any other e-Trike on the market today...This has been an unbiased and unpaid review based on the miracle that my wife has gone from being captive in her own home due to her illness and her restrictive mobility to riding her new Tinniover Trike along the California Coast breathing in the Ocean Breeze as she Experiences the freedom of Mobility once again for as long as my wife has left on this. Earth, we are forever Grateful for the dedication and innovation from the Tinniover Team that has produced such a Superior product in this Day & Age which is the Tinniover Creek Pro-Trike. Buy it,you won't know what your missing until you don't have it! God Bless All,Kimberly and Roy Breedlove
