E Bike Newbie - lock advice

Post by Ren »

Hello. I’m hoping someone can help.

I haven’t rode a bike since I was a child, my car broke down 5days ago and I can’t get to work on public transport, so I have bought a used e-bike! Im collecting at 6pm today.

It is a Fiido 2d e bike.

My first priority is getting a lock. I cannot afford anything expensive for right now as I need to pay for my car but I do need something to secure. Would a D lock or chain be better?
And where do I lock it on this particular bike?!

Also it doesn’t have the rack at the back so I guess I’ll have to carry the lock in a backpack, so it can’t really be too heavy or space consuming.

If anyone could advise if it would be possible to install a rack or storage on this bike?

I would appreciate any advice at all!
Thank you

I would buy a heavy strong lock leave the lock at work. Something like this

Along with a lighter lock if you need to stop for short periods of time at shops etc going to and from work.

Oh thank you so much for replying.

How do I carry that heavy chain when riding bike. I don’t have rear bike rack. Would ii put around the frame?

Also for the lighter would that be a cable lock or one of those d locks?

Thank you again

Also I got the bike- and it’s amazing!! I think I’ve found my new hobby!

The idea is you don't carry it. Wrap round frame/rucsac/whatever. Get it to work. Leave it there.

A good lock for a bike you can't carry anything is a Hoplok.

Don't buy a D lock cos you'll tend not to use it cos it's too much bother to find anything you could get it around. Buy a combination cable lock or chain. I prefer the cable lock as it coils up on it's own so it can hang coiled up ( use last loop ) on the handle bars till you need it. Also it'll loop around most fixed objects. I've often locked my bike to large plastic waste bins outside shops etc. if a thief is determined they'll cut through any lock but handy lock used is better than a super dooper lock unused.

Hi

Thank you for replies.

This is my bike-

Before your replies I found this Halfords cable and d lock but on marketplace and much cheaper- I can afford it! I can get a more expensive chain one in a few weeks but right now not really.

My question is I know the cable loops around the front tyre to the seat, back tyre then the d lock. But on this bike how where would o use the d lock on bike to attach to bike rail? It seems like there’s no place as the frame is wide.

I have found a chain lock, that I can afford but they’re not very long so I wonder if I’d be able to get it through frame, back tyre then post? If anyone knows what length I’d need for a chain that would be great to know.

If anyone can advise on any of it all, I’d really appreciate it. I need to go get shopping and I can’t until I’ve got something to secure bike!

You can possibly get the lock through the carrying handle on the frame (just in front of the seat post adjusting clamp).
If no go, though the black rear fork between the chainset and the bottom of the rear suspension unit.

How secure is your cycle parking at work? Open/busy pubic access needs more security than secure locked cycle pound for employees only. If there is parking indoors, there might be a ban on electric bikes to stop the building being burnt down. E bike fires are a cause of many domestic fires, mostly unregulated imported direct from China ones.

Get to understand the main folding clamp, and the handle bar stem clamp just above the steering bearing. They are similar to Dahon clamps. About half the ones I see at work clamp loose (2 halves of the frame flex/rub against each other when pedalling), because people don't know the tightness is adjustable/can loosen (adjustment is behind the lever).
Remember to top the tyres up every 2 - 4 weeks.

Glad you have found an alternative to the car. Hopefully you can continue to use the bike even when the car is repaired.

Hi

Thank you so much for this reply.

Is the cable lock and d lock not secure enough for leaving in public/supermarkets etc?
If not do I definitely need to go with a heavy chain?

There’s no way I can afford the ones that resist angle grinders.

What if I did a combination of cable and d lock and a heavier chain.

Also would I wrap a heavy chain on my seat post?

Apart from work I wouldn’t leave it in town/supermarket for long- 30mins - an hour tops.

Thank you for your advice on the adjustment I will look into it. Also for tyres - I will :)

I’m hoping to find a rear rack for it.

I definitely intend to become obsessed with biking now- I absolutely love it!! (I know it’s an e-bike, so it’s cheating a little but still I love it!)

Its a folding bike - is there no place you can store it safely at work, without needing to lock it up?

An hour in most towns is probably 59 minutes more than a bike thief needs to nick your bike! No lock, no matter what the cost, will stop a determined thief for very long; just watch on YouTube a few of the tests conducted on them.

Hence why a convenient cable lock is better cos you'll use it even if you leave your bike for a matter of seconds to pop into a shop etc -- there's a saying I don't really understand " a lock only keeps an honest man honest" or "an honest man out".

The best way to deter a bike thief is to make the bike look a bit tatty ( add some bits of PVC tape of different non matching colours etc ) along with a lock the thief will look for something easier to sell. I don't get precious about scratches and add stuff that most won't like my mtb with non suspension forks and home made brackets etc.

A super dooper lock will lead a thief to believe it's something worth nicking whereas a half decent cable lock on a tatty ( looking ) bike is too much risk for reward.

I use a Halfords cable combination lock like this

It's about £30 but you can buy similar from screwfix at a much lower price.
