What did he get? Looking on Jarvik site they seem to be all Mountain Trikes....
He got the road version it seams well built and I think he payed under £ 2000 for it he also has tunal vision and now we can escort him from his house he also has a folding three wheeler and a 4 wheeler that have been relegated to the shed as the electric alowes him to go longer distances we go to the Chester green way and the Wirral way

Yes, I see one for under 2 grand....but only 3 gears.......I have spotted a Jarvik on FB Market place....
Yes it has three gears it is a front hub motor the three speed internal gears is in the middle it has two chain's and a it has a throttle for the steep sections on the ride the gearing is all he needs and you can change gear will stationery

Just come back from holiday with my sister in law.
She has bought one of these:

It is 250w front hub with 15Ah battery. 3 level electric assist with lcd screen. 3 speed nexus hub gear at the point where the two chains meet. Hydraulic discs front and back. Throttle seems to be walk assist only. It folds just in front of the bottom bracket.
Gear change is twist grip and is kind of pre select. You twist to change then pedal backwards to effect the change.
I rode it and it seems solid and well made, but it does have a few quirks.
The rear axle is a split axle so allowing a differential effect. However this means that only the right rear wheel is pedal powered causing a veer to the left under heavy pedalling. Probably not to much cause for concern as most riders would be relying on the motor for most power.
The rear disc is also on the same axle and brakes the right wheel only. This causes a swerve to the right under heavy braking. OK if you're ready for it but disconcerting none the less.
You have to move your upper body around considerably to keep upright. My sister in law shifts her weight around on the saddle leading to her being called Valetino (he of the superbike riding).
Being a step through, you can feel it flexing as it goes over undulations in the road and rear wheels cause the frame to twist.
Gearing seems quite high. Only had it up to about 8mph (I didn't feel comfortable any faster) and the cadence was too slow in first gear. I'm not sure I'd want to ride it at 15mph !
My sister in law rode it down a 4 mile section of the Kennet and Avon canal path and managed very well, especially considering that she has come to cycling only in the last few years (in her 70's) and bought the trike having fallen off her Seago into a canal.
She has adapted very well to the quirks of a trike possibly because she's never been a cyclist.
Many who tried it couldn't ride it. My daughter, a confident cyclist from childhhod, now in her 30's, couldn't ride it at all. I did all right having a pre-understanding of what to expect handling wise - but I didn't like it.

It's because the steering is opposite to that of a bicycle.

On a trike one steers towards the turn direction.

On a bicycle one has to steer slightly away from the turn direction to permit the banking for the turn. Once used to this a trike's steering feels completely wrong.

To get out the canal....and back on a bike.......takes some doing. Our Dog walker knows a few of people down here in Penzance area who have Jorvik Trikes.....they love them......but say they are very hard to get used to..they have known people giving up........I managed to blag this for £750.....6 Gears.......waiting on delivery.......

My friend is strapped into the pedals and has difficulty walking the due to the polio but the cycling has helped a lot with leg strength, the throttle workes on the steep hills and road crossing on his trike also he doesn't have too peddle backwards to change gear he hasn't complained of the bike flexing but I will ask him the next time we are out he bought the trike in June and wouldn't be able to do 20mile rids without it

I bought a S/H Jorvik Classic, 20". Can't get the hang of it at all..as for the throttle getting you up a hill...it's not even walking speed........and If you use the Throttle......Pedal assist cuts out....Is this normal?
