MiRider Gearing, one not GB3

[the1andonly]

here's some heresey. Anyone added any non Mirider gearing to the bike eg a rear derailier or front chainwheel changer and a rear tensioner.
Just thinking outloud. Has any one else had a proper think about it . Allready got 2 so alternatives not an inexpensive option.

Just had a quick look at the wife's MiRider, (early model I think) chain drive (not belt) and doesn't look to have anywhere really suitable for mounting a derailleur, although newer models seem to have two threaded holes in the swing arm, just above the axle ?
Out of curiosity, are you wanting a higher or lower gearing ?
Missus went to a Sustrans open day yesterday and had a go on an electric trike (Jorvik ?) She enjoyed it, but it looked extremely heavy and was only front wheel drive which I'm not a fan of. That sent me down a rabbit hole of checking out other electric trikes, but not one seems to have a differential or crank drive ?
Let me know how you get on, I've got machining facilities here if you need any parts made/modified ?

jockaneezer Thanks for the offer much appreciated.
As to gearing , i really need lower to get up hills without permament full assist (and wife). I'm also used to a much higher cadance. I sometimes find it more difficult to ride than my full susser. If i just reduced the gearing going down hill will be even more just freewheeling. So in a fuller answer if only 3 i would go 2 lower than std with 5 would gear to a max 20mph

Isn't the idea of MiRiders that you use the assist not gears. I know they have now released a geared version.

It is a bit annoying on the way down hills that you can't pedal fast enough.

My experiance is that they may be fine on flat or ex-railway lines but Definitely how short is your piece of string. 20 miles in pembrokeshire around Saundersfoot not particulaly hilly and both of us had to walk last half mile. I could have done it in a 1/2 of the time on my susser no problems (unfortunately doesnt fit in motorhome). The one i find hard to push without assist (not my cadence) really suffers for not having gears.
why not buy the GB3 instead? The wife hates spending money ( from Yorshire) If she'd agreed to spending 2.5k on the GB3 I would have spent even more on Bromptons. The alternative is to buy 2 or 3 more batteries. we have definite range angsity (whatever the words is)

20 miles in Pembrokeshire is good going on a MiRider.

I'm not a stranger to fixed gear as i used fixed wheel (in south Wales then in Midlands, many moons ago) but this is too high a gear for me, i'd sooner spin a bit more and use assist on hills only. As a first stab i will investigate this route first.

You're right about the high gearing, if we cycle back from town, the last section to our village goes through a kissing gate, then straight up a steep hill and there's no way you can actually set off cycling up it. I can set off no problem on my Kalkhoff with the Shimano hub gears in second no problem.

You can get a front changer that mounts behind the bottom bracket but it will depend on a lot of other variables, not least Whether you can fit a double front ring set up, I doubt if rear changer would be viable with the hub motor as there would be no clearance for the block.

What, even using the boost?

What, even using the boost?

I've just fitted more "upright" handlebars to Val's MiRider, so decided to take it for a test drive up that steep hill I mentioned. I "Gave it all she's got Cap'n" and managed to get going, barley keeping above the point of unbalance, but it did manage. The battery display went from 94% to 17% during the struggle, but returned to around 90% once back on the flat and with the boost switched off.
Now that I remember, when I last tried it out, it had been raining heavy and lack of traction was probably the main failure point for being unable to start ?
As ususal, the picture doesn't do full justice to how steep the hill actually is ! It's not quite rope and crampons, but it does give you a workout !

I have never seen the % battery display on ours. Doesn't seem right going so low even if it does recover.
