Follow up about the Vello Bike+ electric folding bike
Hi,
I was originally one of the participants who was positive about the Vello Bike+ electric folding bike, however with hindsight I now recommend that people avoid this bike.
I have had continuous problems with the bike since I got it three years ago; the biggest previously were (1) when the motor charging terminal fell off because they hadn't glued it on (that took months to get fixed), and (2) when the belt snapped while I was at a junction on a major road (Gates, the belt maker, says the fault is with the bike design, which doesn't allow the wheel to be moved forward so the belt can be removed without twisting it). It has spent months off the road while Vello / Zehus got around to sending replacement parts. The drop-out screws have also snapped twice, which Gates also suggested was a possible reason for the belt snapping.
Now... the entire rear wheel shifts from side to side while I am cycling, which is because part of the folding axle is not connecting. Either it is broken or loose, however I cannot get at it to see because of a bolt that is fixed in place with permanent locktite. Vello spent four weeks of ignoring me - apart from telling me to point a hairdrier at the bolt (which I tried) - and now they tell me that I must arrange a courier and pay for it to be transported to them in Austria, from the UK, in order for them to have a look at it.
That response is despite there supposedly being a 5 year frame & fork warranty on the bike - and this is NOT a cheap bike.

Gosh it sure sounds like a major PITA to deal with Vello Bike. Sorry you have to go through that.
My intial experience with Vello was less than promising so I steered clear of buying Vello bike with Alfine 11 hub that I was interested in. I posted the following in another thread a while back.
"Vello's support absolutely sucks. I've sent multiple emails to them, and a Vello distributor even emailed them for me, but neither he nor I got a response. The bikes might be great, but just ignoring emails, including from one of your distributors, is a big no no in my book."

After telling me I must arrange delivery to them, and me kicking up a fuss, Vello then told me that they didn't meant to cause confusion but that they "cannot" arrange delivery from UK. They mentioned that they would usually have me return it to the retailer, who has since stopped selling bikes.
They suggested that I could find a retailer who could look at the bike. That left me somewhat restricted as (1) the bike is my main mode of transport since the pandemic started, and (2) I only live near to a Halfords store.
So I took it into the Halfords store over the weekend; two mechanics looked at it. They think that some bearings might have gone in the axle. They are checking the details for the Schlumpf gear before they do anything to the bike. Unfortunately they aren't allowed to talk to the manufacturer directly - company policy.

I didn't, but I really don't mind either way. As I say, I have had so many problems with this bike, and it has been unridable for so many months due to Vello and/or Zehus taking their time to send replacement parts. Plus, it has been expensive, such as buying a new belt after only two years of use.

Anyway, all documents, including a brilliant workbench manual, are here:
schlumpfdrive.com/technical-documents
Honestly, I feel somewhat ashamed for my countryman's actions...

Personally, I can't believe that the excellent Schlumpf drive could be faulty and I'm curious what they'll check.

schlumpfdrive.com/technical-documents
This sentence correlates to Vello/Zehus, but not Schlumpfdrive/Haberstock-mobility - correct?

Sorry, there went something wrong with the link above (which I can't fix?).
They have to be careful while removing the cranks, the rest of the drive should be easy to remove.
Please try this:
hXXp://www.schlumpfdrive.com/index.php/technical-documents.html
(Replace the two "X" with "t".)

I agree the frame design just hasn't been thought through and tested. When I have tried to do maintenance, everything has permanent lock-tite. I've previously posted my experience of the folding mechanism being unsafe unless additional restraints are added.
From your experience, should I replace it or toss the bike? I feel like I'm throwing good money after bad.

Red loctite breaks down with heat, 500F or 250C. Needs a torch.
I never liked Vello's grandiose claims about riding without charging. Figured they couldn't be trusted.

Actually, its a claim of Zehus.
The Zehus all in one rear wheel is a quick (and probably dirty) solution to transform any bike in an eBike.
Several manufacturers use the Zehus solution.
All those bikes suffer from the same problems.

If you see the video; the side of the joint that is moving is tucked behind the Schlumpfdrive, so is not accessible without removing it. Vello suggested removing the bolt from the other side, but that is fixed in place with permanent locktite. The Halfords mechanics confirmed they have no magic way to remove permanent locktite without damaging the rest of the bike - I already tried holding a soldering iron against the bolt for 30mins. They believe that there may be a bearing that has gone, but they will only be able to verify if that is correct if they can remove the Schlumpfdrive first.

The main problem is the concept: regeneration doesn't produce enough energy for enough electric assist and the full integration of the assist in the rear wheel only allow a small capacity battery.
Either, there is a very weak assist or the assist is very limited in time/distance.
And this is a major problem on a single speed bike because the pedaling on a single speed is less efficient than with a 9, 19, 11s speed bike and the assist is more used on a single speed than on a multiple speed bike. The single speed issue could have been improved now because i read there will be a Zehus wheel with a 4s cassette but the limited amount of energy produced by regeneration and the small battery capacity remain.
The two speed of the Schlumpf doesn't replace a cassette or an internal gear hub.
Then there are (or at least were, I have no very recent information about this) problems with the Zehus web server that is needed to control the hub. With the original Zehus rear wheel, the control of the hub was not with a direct wireless link (BTLE or similar) from the smartphone to the wheel but was going over internet to the Zehus server and then back to the wheel -> no internet (or server down) = no hub control.

So, Vello fixed the fault. They haven't told me what it was, but I am assuming it was the bearing as everyone else said. They returned the bike to me on 23rd August 2021 and I was able to reassemble the parts on 28th August.
So, as a round trip it took Vello 8 weeks to fix a broken bearing. And the bike has been unusable for 180 days out of 1178 = 2 in 13 days.

I was really considering buying the Vello bike+, but after reading this thread, I'm not so sure any more.
I did test the GoCycle G4, the Carbo, the Bromptons ebike and the Vello bike+. The GoCycle G4 and the Vello bike+ were the best ones in my opinion.

Hey StuartB, could you tell me how your experience with Vello has been so far after they fixed the bike?

Seems to be two problems with Vello+.
The lack of after sale support of the seller VelloBike (can't really call VolloBile the manufacturer since they only assemble the Bike, all parts including the frame come from several places in Asia).
About this, I discussed with a couple of resselers in Belgium who were selling the Vellobike folding bikes and they all stop selling it due to many problems with Vellobike.
And the Zehus all integrated ebike wheel.
The problem with this wheel is that the concept is wrong.
Its not possible to have enough energy generated by regeneration to provide a real ebike assist and the battery has a very small capacity resulting in either in very limited ebike assist level or higher ebike assist level but during a very short distance.
Moreover, the Zehus wheel of the Vellobike is single speed, so the bike absolutely need quite a lot of ebike assist to be usable which is in contradiction with the very limited amount of ebike power available in the small battery and from regeneration. Without ebike assist its a kind of inefficient single speed bike.
Developing a good folding ebike is difficult because being a folding bike, weight must remain low to allow a normal user to carry the bike folded and a good ebike assist add at least 4 to 5kg with a big enough battery (if you look at the announced weight of Ahooga for instance, its low because the announced weight is with the smallest, actually too small battery, they have a bigger battery but then the weight isn't so low anymore).
The Brompton solution has a limited added weight with a 300Wh battery not as big as on full size ebike but big enough for commuting.
