Lovely day here today so went for a spin down to the sea. I’ve only put 120kms on it so far thanks to lockdown but it’s all good so far. It gets a good few admiring glances (deffo the bike rather than me!).

Pure class

DD is physically bigger. No way that's a DD in that picture. And while most motors of road legal ebikes can do an awful lot more than 250W, their controllers are usually restricted to 7A (for a 36V setup), giving 250W max output of the system. I've seen many of them.

Feck out the controller and replace it with a €15 30A from China and then you're talking (over a kW)

Could anyone recommend a conversion kit for a daily commuter 10km each way? Hybrid bike. Thanks

Really? What did you get for the money?

2 already decent bikes adapted to ebike - good job that I am happy with - as simple as it may be, I do not possess the technical ability to adapt my own bikes. Yes, I am sure it would have been cheaper and next time I need my car serviced I will buy the parts and do that myself too - i know my limits and will pay others to do what I can't or don't want to, even if I spend more occasionally:D

The amount I paid though appeared in line with other quotes I got and I looked up battery types etc so I am satisfied with what was installed.

The bikes both ride lovely (which is ultimately what I wanted), have good range and power and overall cost me significantly less than an equivalent bike from a store in e-bike form.

My Kuma M1 finally arrived.
It's a lovely looking bike. I specifically ordered the black as I wanted it to look as "ordinary" as possible. The rack and bag in the pic detracts from its looks tbh.

Cycling it is great fun. I put it on the highest power setting and gave my wife a go. She couldn't stop laughing. It's quite exhilarating.

As an ebike novice, I can't really assess how it compares to other bikes. Certainly on level 5 assist, it's very nippy and ordinary inclines are no bother. Go down to level 1 and there's not a lot happening. I tackled a couple of very steep hills and in level 5 it went up them fine. I mean, it still required extra effort from me and I wasn't bombing up them but it went up steadily and I wasn't panting or anything. These are the type of hills where you'd just get off and walk if you were on an ordinary bike.
I've also cycled it with the motor off. It's a heavy bike so you notice it but it's actually grand and cycles fine. No real drag with motor off. I sometimes just switch it off when coming downhill.

I took it out to Bray today (I'm in Shankill) and went to the base of Bray Head. Then came back and thought, feck it, and went up Killiney Hill. Back home now and it really wasn't much effort at all.

Thinking of picking up the Kuma R1.

Does anyone have any experience?

Just an edit...

after some more research it's either the Kuma R1 or a the VanMoof s3.

I’ve ordered the R1, using bike to work scheme - it’s due for delivery to me next week so I might put up review once I try it out;
I only saw the bike after browsing this forum and once price came down in sale I decided to go for it - my limit was 1,500 as that’s all the scheme allows for.
I am very occasional bike user so not sure if this will give me enough ‘help’ but I’m hoping it will be enough to encourage me to get on the road more during the summer months.
I don’t live in Dublin so I wasn’t able to try it out before buying it - fingers crossed that I made the right choice, the bike looks lovely and reviews seem good so far.

Well wear, sure is a neat looking bike!

What torque has that motor ?

How much was it again ?

M1 is 2068 on sale atm. Think their new range is due out soon.

Did you use Travelhub?

Yep

Ugh
Although, that means I probably wouldn't have been able to afford the new model anyway.

How long did it take between uploading quote on Travelhub, to getting the bike?



Yeah new one will retail at over €2,600. I think the biggest changes is introduction of a belt to replace chain and the lights will now be integrated into bike (I thought they were already?)

1 month.

Where are you getting your info about new models?
The light is integrated on the R1 but not the M1.
They're modest enough changes anyway so not too worried.

I have been having a barney with Jorvik, a UK supplier of e-bikes. I bought a tricycle from them about 2 years ago and it worked fine, a bit underpowered but street legal.

I didn't use it for a period before christmas - it had been working fine, and I kept it indoors until about a month ago, when I would not start, battery charged etc.

I finally sent the front wheel back to Jorvik and they said I needed a new motor, the other one was rusted.... I questioned how a bike that is designed to be ridden in wet conditions could have that issue and here is the reply I got -

"All electric cycles (made by us or otherwise) are not completely waterproof and all manufacturers will advise not to get them saturated and if they are used in the rain to dry them for storage.

All cycles are susceptible to rust if not kept in a dry location and - we can't comment on the conditions each tricycle are kept. Electrical items used outdoors such as lawnmowers will rust if allowed to get wet and not dried. We have not replaced a motor due to rust and no cycle manufacturer will list rust a warranty term.…"

What is "storage" are they saying that if you bring it in from the street you have to dry it??

They sent a photo, of the motor.... attached file (.png)

Are they having a laugh?

I got the Vanmoof via the bike to work scheme (using Travelhub) so it can be done. Two invoices, one for me, one for work.



I’m only a couple of minutes away from you with my S3, if we ever bump into each other on the N11 cycle lane, it’s on.

I'll keep an eye out for you!
That said, I often get lost on the N11 bike lanes. It's a meandering mess of potholes and pedestrians.

I am on the lookout for a front hub conversion kit but find it difficult to find anything with over 30 N.m torque. I came across this today.

Anyone heard of these Guys? Any issues with 48V as opposed to 36V?

I ordered this but i dont think the battery unit will fit in where the bottle holder is. If this is the case what can i do?
