I bought a Bajaboard in a used condition of 250km. Those 250km are real and It was driven in a time of just 2 months. Of course there is a chance of having bought a board which was not in good hands, but the preowner made a good impression on me. So no reason to think about that too much.
So the bad thing about the bajaboard is that everytime I rode, something got broken.
Some examples of failures/bad engineering and the solution:
- motor mount screws get loose and block the motor pulley -> they need to be screwed-in with a threadlocker/glue
- belts dont last long because of stones getting between belt and motorpulley -> here has to be a cover protecting from dirt, stones etc.
- wishbones make loud noise, because they are worn out after a short time (200km) -> using higher quality wishbones like IGUS GFM-0810-07
- outer side driveshaft bolt got broken-> using stronger ones
- inner side driveshaft bolts worn out-> using stronger ones
- lock ring on one motor did not hold and let the rotor move in and out -> correct mounting
- battery, bms and cables under battery loose inside of board, terrible cable management-> improving cable mangement and building a covered mount for bms
- old version of drive shaft constant velocity joint rubber boots fall of from driveshaft joint because of no possibility to fix them in position (the three small ones in the following picture) -> new version now has a possibility to use a zip tie
belts make loud sounds-> changing materials
one controller did not work-> got a new one from bajaboard because of warranty, but the new one had a loosen Pin in one of the connectors-> quality control improvements
ball joints are worn out too quick -> using higher quality
screws of ball joints under journals got loose, because of bad (white) glue put on them -> using higher quality thread locker
too much play between plastic wheel and 5 edge mount-> higher material quality and production tolerances
Here is a video of the worn out parts:
controllerdisplay not bright enough -> using brighter LEDs for display
real range of the board when driving mixed is 20km, not 30km. When reaching 35% battery status, no more high power available
breaking when roling down a mountain, when board was standing still for some seconds before, sometimes does not work, thats very dangerous!
lights don´t light you the way, they are just for beeing seen by others
acceleration the first meters is boring, just after reaching some speed, acceleration is fun
hand controller is great itself, except from the display
going uphill never made problems
when board is adjusted to a small turining radius and soft dampers-> dont drive over 40km/h because of being uncontrollable by wobbeling
For normal driving the electrical differential and drift mode are the only modes that make useful sense for experienced drivers.
All the other functions like power limit, brake strength, launch control, traction control are just for beginners. I dont see any useful reason of using burnout mode.
All in all price and quality of that board don´t fit together. 4500€ is way too much for the bad quality you pay for. If you are about to use the bajaboard in offroad terrain, you will be wasting lots of time in maintenence like repairing and putting money in spare parts. On road use makes more sense for this board, but thats relatively boring. To my mind the bajaboard GX4 2017 still is a beta tester board. For example, if you take a look at generation 3 you see better quality in suspension arms (cnc machined). On the 2018 model front motors got smaler etc. etc.
