Wheelchair electromo

[JenR]

Hi everyone,

I have been using a Stricker Electrolomo for 2 years now on my wheelchair.
Details can be seen here: Electro lomo
It is a sort of attachment that you just click on your wheelchair and off you go!

This is me riding it:

I am very happy with the electrolomo but... The maximum speed is about 9mph. I would like to be able to go faster, so I can join my friends on bike rides (they go faster).

The electrolomo has a Heinzmann hub motor, 250W, 197 rpm, 24V and 16inch wheels.
I think it is a geared motor, it has a lot of torque at low speeds.
Here is a picture of the motor:

Currently I have 2 sets of 24v batteries. When one is empty, I switch to the next set.

Now, is it possible to go faster with this motor?
The motor says 197rpm, I have a 16inch wheel. If a 16inch wheel goes at 197rpm, it is about 9mph.
I think it would go faster with a bigger wheel, but a bigger wheel doesn't fit.
Would more Volts make the motor faster or would it still go 197rpm? I could connect the two battery sets so I have 48V...

Hi YES the motor will run faster DON'T connect 48 volts it will GO BANG

I suggest you Email Heinzmann direct and ask if you change the controller and battery to 36 volts will the motor cope and get them to quote for the parts They have different capacity battery's it depends on the range you need and the price you want to pay once the confirm the motor is OK on 36 volts we can all advise you on where to find cheaper controllers and battery's
If you cant use the motor they can supply a complete new kit

Thanks Mike!

I sent an email to Heinzmann, let's see what they say

36 volts will give you about 13 mph with the corresponding increase in motor revs. Sadly though, the law doesn't permit this in the UK. As a mobility vehicle it's limited to 8 mph on the public highway, your 1 mph excess not relevant since 10% speed limit tolerances are allowed. But of course 13 mph is a different matter entirely since it would then have to be type approved and registered as a motor vehicle.

E-bikes and e-trikes are exempted from that by having working pedals and conforming to 40/60 kilo weight limits respectively.

I live in Belgium, I don't know the exact laws here.
I do know that E-bikes can go 15mph in Belgium, but this isn't really an e-bike since it is purely powered by the motor.

Edit: I just found online that the maximum speed of electrical wheelchairs is 18kmh (11.2mph). This would already be significantly faster than the current 9mph.

That's good Jen, your law for wheelchairs is much less restrictive than ours so you shouldn't have a problem. Here in the UK it's 4 mph on footpaths and 8 mph on roads.

I've seen a similar motorised wheelchair being used a few times.

Someone connected with the e-bike motor and mobility dealer Team Hybrid uses one, saw it at an e-bike show at New Milton in Hampshire.
