Where to buy? http://www.kuberg.com/p-2-start.aspx
Been sorta meaning to do this for awhile but just haven't gotten around
to it. I bought my 2 year, 10 months kid a Kuberg Start this past 2013
Xmas and think I've had enough time playing with it to give a summary.
He just turned 3 and is riding it nearly everyday.
About the Start: Kuberg suggests this bike for riders aged 3-5 but I can
see where slightly older or slightly younger would be fine - really
just depends on your kid and you know them better than I do. Mine is a
little bruiser and has been bombing big dirt hills on his Strider for
months now - without brakes! His mom is forbidden to come with us on
these rides. I wouldn't have hesitated getting him the Start a bit
earlier but Christmas is a good excuse to drop $1200 on your kid. A lot
right? Well a new gas powered 50 is about the same price, but there's a
huge market of used gas 50's will run you around $600, and you can sell
it when he's outgrown it for probably about the same. These electrics
are in short supply in the used market, and from what I've seen are
usually only about $200 cheaper than new. So most likely its a small
investment to get your 3 year old on a bike 2 years earlier than the
other kids. Even if you plan to go with a 2x heavier gas bike, the
lowest seat height I found was 19.1" on the PW50, so you're looking at
age 4 or 5 being the youngest you can start your rider on a gas bike.
Plus unless you live out in the sticks, your kid is gonna get a ton of
seat time on an electric bike. Garage? Backyard? No problem. Living
room? Eh maybe when mom is at the store...
1st question: Oset or Kuberg? I did a lot of research beforehand, and
while the Oset is vastly more popular (indeed I was 100% sold on getting
one), once I'd seen both bikes in person the choice was obviously
Kuberg. The construction is of considerably higher quality and the cost
is only $50 more. Don't get me wrong, the Oset is a nice bike and its
good for the industry to have brands competing. I just personally felt
that the Kuberg was a nicer bike for the money. For the smallest bikes, both brands are trials bikes - which is great since this gives them a much lower seat height than their gas cousins. For the rest of the product line, Oset has stuck with trials while Kuberg has gone a slightly more motocross route, although currently Kuberg and not Oset has an adult sized trials bike coming to market. Confused? Just look at the product line of each bike and you'll understand what I mean.
Kuberg customer service
is amazing. I've heard that Oset shares this trait so with either bike,
rest assured that any issues or questions you have will be dealt with
usually the same day.
Packaging: Although well packaged, mine still came damaged. The box
appeared to have been dropped repeatedly on the front forks. They were
rolled over/rotated, but I was able to [mostly] straighten them. They
don't travel very well but my kid is still too light to really make them
travel so its not a huge concern just yet. Good thing too, as UPS is
still figuring out how to handle my claim. The front wheel and front
fender which aren't attached to the bike during shipping were also
damaged but I was able to true them up to useable condition.
Assembly: Handlebars and front wheel/fender pretty much sum up the
assembly. I think I spent about 7 minutes once I'd gotten all the parts
unbent. Assembling Ikea furniture is harder than getting one of these
bikes assembled.
Manual: Very good IMO. Instructions are very clear and cover basic
maintenance and upkeep as well as tips for teaching a 1st time rider.
Mods: Despite having ridden a Strider since he turned 2, my kid was
pretty nervous about the Start at first. He'd putt around but didn't
like that he couldn't touch very well and the throttle/braking was
rather lost on him. On the lowest speed setting balance is a serious
issue since top speed is only about 2-2.5 mph on flat pavement. On
hills/dirt/grass setting #1 is useless. The bike just sits there and
hums. Setting #2 is great for hills/dirt/grass but is about 6-7 mph on
flat pavement.
The speed selector button requires a 2 hand process. Its unlikely the
little ones will be able to figure it out if you keep it subtle. Mine is
a little problem solver and presses the button all the time trying to
make it faster but doesn't realize it must be done in conjunction with
the handlebar switch. The bike will remember the last setting used so
you really won't have to mess with it. We did since we had to stick with
#1 for pavement, then bump it up to #2 once we got on grass at the
local park. Kuberg lists the top speed of the Start as 15mph/24Km/h. I
stuck my 100 lb wife on it to test that on speed #5 and would say that's
about accurate. Sustained use at max speed, you can expect about 1 hour
of battery life for a child rider, less if your wife refuses to get
off. At setting #2 (about 6-7 mph on flat concrete), we ride about 0.5
miles to a park, tear up all over the soccer field and some small grass
hills for about an hour, and 0.5 miles home. The battery is usually
around 60% full after that and is recharged in about an hour.
Anyway my solution was to make some training wheels until he got used to
the power and controls. He's ready to remove them by now, so we're
having chats about it every time we go ride. He gets his stubbornness
from his mother.
He also thinks its funny to try and ditch us. He'll take off on his
strider and try to find a way to lose you. Obviously then, we got a
remote cutoff switch for his Kuberg from
http://www.3built.com.
I went with the universal one that comes with a 4AA battery pack but it
looks as though they have one that will run on a 24v system now.
That's the cutoff mounted to the front of the upper battery (right side
of pic), and the battery pack mounted to the rear of the lower battery.
The charging plug is mounted under the subframe on the left side of the
pic, directly above the motor. Its well protected during riding although
it is in the most natural position to grab when you have to pick the
bike up. Thankfully the mounting tab is pretty stout so I haven't bent
it yet.
And the remote:
Weight loss: If nothing else, this is why you go electric and not gas! Even as a 33 lb 2 year old, my kid was able to pick the bike up off the ground by himself. However, at 44lbs, the Start is still 11 lbs heavier than my kid. I
found some info on converting it over to LiPo batteries for a 9.5lb or
23% overall bike weight reduction. Cost is about $200. Plus the
batteries are smaller so they'll only take up the bottom half of the
lower battery tray, thereby lowering the center of gravity a fair bit.
Going to be doing that in the next month. Many thanks to the Oset owners
for doing all the R&D to come up with a way to do this conversion.
Also I'm thinking of hacking off the kickstand since its steel and not
really needed IMO.
Controls: It took my kid a couple rides to the park to really figure out
the whole throttle/brake idea. The Kuberg has allen set screws to
really adjust the levers down to the bars so don't worry about your
kid's hands being too small to reach. Mine has rather dainty hands and
he can use both brakes without taking his hands off the bars no problem.
Just be warned, if you snug these levers up this much, you better have
some very true wheels or your front brake will be rubbing. The rear is a
band brake so no biggie there, but keep it true anyway.
Kill switch and battery level indicator
But we're in the US where MX is KING!
No problem. For about $80, we added a MX seat. Swapping em out takes a
3mm allen wrench and about 90 seconds. But it does add some considerable
height to the seat putting it more on par with the seat height on the
50's:
More on Battery Life: Kuberg sells 12v, 9Ah batteries for about $50 each and the Start requires two. You can find the same batteries on Amazon for $20 each. In case you're not really fluent in electrospeak just think of it like water. 9Ah is the capacity, or size of the bucket. 12v is the size of the hose on the bottom of the bucket, but since the batteries are wired in series, its actually a 24 volt hose leading to the motor. Don't worry about it too much, just know that you can use any 12v battery that fits in the tray. 9Ah batteries will give you stock run time - which is more than adequate for kids. If you have the odd kid that rides non-stop all day, then invest $40 for a second set of batteries. Hook them up to a battery tender while he's wearing down the pair in the bike. Swapping out batteries is a 10 minute job. Likely however, you'll find that your kid will want to take breaks occasionally - when he does, just pop it on the charger and it will most likely be full by the time he's ready to ride again. They're sealed lead acid batteries, so you're not going to hurt them by charging too frequently or when they're barely below full capacity. Using this method, my kid has yet to drop the batteries even to the last warning light (1/3 capacity) despite riding all over camp all weekend long.
Overall Impression: Great little bike for the young ones. At less than
half the weight, nearly no maintenance, and no hot parts - I'm
definitely sold on electric instead of gas. The 50's are dead IMO,
electric is such a better platform for young riders. As far as Oset vs.
Kuberg goes, I really truly hope that Oset gets away from Chinese
production so that I have a competitive choice to make when my son
outgrows his Start. My only complaints about the Start is that power
setting #1 is just a bit too anemic, and #2 is a pretty considerable
increase. I'd like to see #1 increased by 1mph or so just to make it
usable without training wheels. Secondly the suspension is pretty hefty
for young riders. I'm not sure if new forks will improve the front or
not. As is, they're stiff and sticky. The rear spring is just too
heavy for kids. Even my 100lb wife doesn't bottom it out when standing
on the bike with the preload dialed all the way out. Finally, I've noticed a bit of excessive twist on the swingarm with the training wheels installed. I'd like to see the rear motor/swingarm brace replaced with square tube instead of flat bar to rectify this.
I wanted to add some action shots and some pics of the plastics removed
so folks can get an idea of what's involved on these bikes:
Chain guard does a nice job of protecting your offspring from the
rotating parts, but good parenting does an even better job. Chain
adjustment is a 2 minute affair and since the motor is mounted on the
swingarm you just snug it up just right and call it good. Spin the wheel
after you tighten it, if its noisy, loosen it a bit.
Even with the preload fully loosened the suspension is really stiff for
my 33lb kid. He doesn't seem to mind but a lighter spring option would
be nice. The front forks are non-adjustable and mine stick a lot,
although I suspect this is due in part to the damage done by UPS. Good
view of the charging jack located under the seat on the right side of
the bike.
Magnetic kill switch lanyard. A nice touch. Comes standard with a wrist
lanyard. We added a small carabiner to ours so we can attach it to his
waistband and leave his hands free.
Heim joint swingarm pivots. Really a nice touch. I've read that Oset has
some issues here as they use a cheap plastic sleeve rather than a
bushing.
Two 12v 8Ah batteries supply the power. Being sealed lead acid they're
maintenance free and you can plug the bike into the charger after every
ride if you choose to. Unfortunately at 6.5lbs each, they're pretty
heavy. You can DIY swap in a pair of 5000mAh 6S LiPo's (at about $50
each) and drop 9.5 lbs. Unfortunately they're a bit more needy when it
comes time to recharge so you really should remove them from the bike
and you have to use a LiPo specific charger. Its more involved than the
stock SLA's, but a nice option if you don't mind the added hassle. The
bundle of yellow/green/red wire on the left is leftovers from the remote
cutoff that I left stock length in case I need to move it to his next
bike and need a longer run.
Gavin has discovered that he can spin the rear wheel on wet cement if he
turns hard and punches it. He spent an hour doing it (notice all the
tire tracks). Bike was still going strong when we got home but I put it
on the charger anyway. Recharge time: about 15 minutes. We live in a
gated community with a lot of retirees. Our HOA actually has a ban on
Power Wheels types of toys because of the noise. No issue with the
Kuberg. I've even had an HOA member come out and ask what I did to make
it so quiet. "Spent a lot of money," I replied. Haha.
This is why you want one of these bikes. Can't get any more genuine than that.
