Oset trials bike (kids)

Post by mikedufty » Sat, 10 Jan 2009, 08:30

I've just bought an OSET spider 16 electric kids trials bike.
Not a road going vehicle, and only suitable for riders under 40kg, but one of few electric vehicles to be very competitive in motorsport against ICE equivalents.

It has a 600W 24V motor, powered from 2 small sealed lead acid batteries. Running gear is mostly bicycle parts, kids 16" wheels. Adjustable speed limiter for learning and riding in backyards/indoors.

Trials is a sport where a course is taped over difficult terrain and the object is to get around without putting a foot down or crossing the tape, so speed is not important, but good torque for the vertical bits and balance are.

At the moment my 5 year old son puts his feet down to do a U turn and has fun just riding back and forth, but there is the option to get into trials if that gets boring.

Plenty of scope to look into mods like Lithium batteries if we reach the limits of the standard bike some day.

Some pics here of my son trying it out at Margaret River

The motor is mounted on the swingarm, just behind the pivot, so the chain tension isn't affected by suspension movement. Motor is a rare-earth neodymium, 24V 600W unit according to their web page.
$99.95 as a spare part

The US online store is pretty good, you could pretty just about buy a whole bikes worth of parts for about the same cost as the bike.

At the moment more power is the last thing it needs, heaps of wheelspin even with the speed control turned right down. Once Patrick gets to the point it can be derestricted we'll start thinking about upgrades. The factory does a 36V 750W upgrade. The works bike also uses 80amp controller instead of 40 (details in the christmas newsletter link on the front oset page).
They are mostly made from cheap chinese bicycle parts, but well selected and put together so you seem to get a really capable bike at a good price, mine cost $1330 delivered, about the same as my pushbike.
