Hello, Newbie here and with the Daywins MG 1703 Tricycle, just one of many similar Chinese brands now. I chose this 20 inch wheel 4 inch fat tire model (most brands have a 24 inch wheel) with the Bafang 750w motor in order to have the best acceleration. ( could the 20 inch be the cause?) I assembled it yesterday and tested it without power. It has the Shimano 7 gear cassette.
I had studied various videos of different brands for half a year as reviews by competent bike reviewers. NONE had mentioned steering problems so I thought I had no reason to reject this brand except there was no actual video review of the 1703. Here is the problem:
Upon pedalling gently without power within 5ft. it starts to turn on its own either left or right and heads for the ditch. It is simply impossible to merely correct it by turning the other way. It does this every time I try. I have to brake get off and walk it onto the driveway. If I had enough space it would keep turning in a circle!
I carefully followed the assembly video and today noticed I was 1/4 inch off on the bracket connecting the rear wheel assembly so I triangulated a measurement from the axle to the seat post frame but upon testing again the same unwanted turning happened. I'm now thinking its the rounded fat tire from side to side. I am thinking it is the tiller stem to fork which may be too vertical. Should have more rake? This, in conjunction with the bike being too short? ( 49 in wheelbase). I recall about 15 years ago I came across a vendor owner selling his own tricycle brand and when I attempted to pedal in the tent the same thing happened. It would not steer straight in a few feet and veered like this one. I told him then the rake needed to be greater on the short bike. Now, since NO ONE reviewing these bikes that I have seen recently have said one word about this I thought maybe there is no issue now.
I submit that it is not a mere matter of learning how to ride a trike. For the above reasons I believe it a design flaw. My bike is useless and I have told my vendor and the Daywins manufacture that I should be given a full refund with no shipping or restock 20% fee. I even ripped the box off to get the parts out. I told them I would not even give it away and have some one get hurt or killed on the road. Ungodly awful. I had planned to drive 5 miles to the grocery to eventually save on gas. I live in my trailer and my Ram v10 gets about 10mpg.
Your experience would be appreciated.
